When water comes in contact with chocolate, dry particles begin to stick together, forming a rough paste. Since water has a high specific heat capacity, it requires 4.184J of energy to raise 1g of water by 1 degree celsius. By using steam as a heat source, heat will be transferred more gently and evenly as steam requires 1.996J of energy to raise 1g of water by 1 degree celsius.]]> 2022-04-20 15:26:50 UTC https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2150543635 chloe https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2151492369 double boiling involves a bowl of chocolate being placed over a pot of heated water. the steam from the heated water will rise up and gradually heat the chocolate. since water has a high heat capacity, its temperature will not change drastically within a short period of time thus ensuring that the temperature of the chocolate will not suddenly rise and cause it to burn. exposing chocolate to very high temperatures can also cause fat bloom which is where the fats in the chocolate melt and rise to the surface of the chocolate. once the chocolate cools, the fats set which causes white, waxy spots to form. thus, using double boiling allows for steady and gentle heating of chocolate by using indirect heat to prevent burning or fat blooming.

The double boiler produces the slow, indirect heat that these delicate foods require. Melting chocolate using indirect heat, steam, helps to heat and melt the chocolate more gradually. As the water heats up and steam is released, the steam stays trapped between the two pots, which then heats the food in the top pot. The high specific heat of water also helps regulate the rate of heat transfer between the water and chocolate at a slower rate. Chocolate has a melting point close to 36°C. It changes from a solid to a liquid very quickly.

As the specific heat capacity of the pans are low , the temperature will increase too quickly and will burn the chocolate .

Double boiling helps to melt the chocolate more gradually which greatly reduces the risk of overheating the chocolate or causing fat bloom. Since water has a high specific heat capacity of 4.184 J/g.K, this means that it takes more energy to raise its temperature. However, the pan has a low specific capacity, meaning it absorbs heat quickly and will burn the chocolate. To prevent that, double boiling the chocolate will be the best method to melt chocolate as give that silky smooth texture and not ruin it.

Since water has a higher specific heat capacity of 4.184 J/ g. K as compared to that of stainless steel of 0.500 J/g.K, it requires a longer time to raise the temperature of 1g of chocolate by 1℃.

water has a higher specific heat capacity than chocolate and the pan. as a result, with the same time taken when heating, the chocolate and the pan will gain heat and increase in temperature faster than the water and hence the chocolate may burn quickly. therefore in double boiling, water is used for better control of the temperature so that the chocolate will not burn so easily.]]> 2022-04-22 16:26:46 UTC https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2153838997 sin hwee https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2154316584 in double boiling, water is poured into a pot that sits on top off the burner and a glass or metal bowl containing the chocolate is placed on top of the pot. this method allows the steam from the water to heat up the chocolate indirectly, making it a more gentle method to melt chocolate. this also lets you have more control over the heating process as compared to directly melting it in a stainless steel pot. since the stainless steel has a specific heat capacity of 0.500 J/gK this means that stainless steel require little energy to increase its temperature, making it easier for the temperature to increase faster and making it harder to control the temperature which may cause the chocolate to burn. meanwhile, water has a higher specific heat capacity of 4.184 J/gK which means more energy is required to increase its temperature and the process of heating the water up will be slower, allowing more control over the heating process.]]> 2022-04-23 03:00:53 UTC https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2154316584 Suo Jie https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2154326974 Chocolate is sensitive to heat, so double boiling allows the melting of chocolate using indirect heat (steam from the water beneath) instead of direct heat from the stove. The indirect heat helps to melt the chocolate slowly and evenly which reduces the risk of overheating the chocolate.
Chocolate is also sensitive to moisture, double boiling using the mixing bowl and saucepan creates a "seal" that will trap steam within the saucepan, this prevents the steam from reaching the chocolate.
The specific heat capacity of water is higher than that of chocolate, double boiling is able to melt the chocolate much faster without bringing the water to a boil since lesser energy is needed to raise the temperature of chocolate as compared to water. The specific heat capacity of water is higher than stainless steel, melting chocolate using stainless steel can cause overheating because it gains heat faster than water.]]> 2022-04-23 03:22:55 UTC https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2154326974 tze xin https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2154351848 Chocolate has a relatively low heat capacity. Hence, less energy is needed to cause it to melt. Stainless steel has a heat capacity of 0.5J/g.K. Hence, it heats up very quickly. Before chocolate in the pan has achieved the sufficient energy needed to melt, the pan could already contain much more energy which would burn the chocolate that is being melted in it. Double boiling allows the chocolate to heat up at a slower rate, and allowing it to melt without being burnt. ]]> 2022-04-23 04:12:09 UTC https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2154351848 Ng Jia Qi https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2154353642 Double boiling uses steam to heat up and melt the chocolate gradually instead of using the direct flame, reducing the risk of overboiling the chocolate.

When being melted using direct heat, it can cause the quality to deteriorate. Double boiling is needed to produce gentle, indirect heat. The specific heat capacity of water is 4.184 J/g K, which is higher than that of a stainless steel pot (0.5 J/g K) that is normally used for double boiling.

Double boilers on the other hand, works by using the steam from the hot water in the bottom pot to heat the top pot. In this case, the chocolates are not boiled under direct heat but indirectly through (steam heat). As the specific heat capacity of water is high (4.184 J/ g. K), it means that it will take a longer time for water to heat up and thus provide precise temperature control with even, radiant heat.

This means that chocolate will require lesser energy as compared to water and gets heated up faster. When chocolate is melted by double boiling, it uses the indirect heat from the steam generated by the simmering water instead of direct heat from the stove to melt. This allows a better control over the rate at which the chocolate is melted. The chocolate will then melt more gradually which reduces the risk of overheating and burning resulting in an undesirable taste and texture of the chocolate. ]]> 2022-04-23 06:22:51 UTC https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2154396722 Tifanie https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2154404395 When u double boil the chocolate, 4.184J of energy is needed in order to raise 1g of water by 1 Degrees Celsius. On the other hand, if double boiling is not involved, only 0.500J of energy is needed in order to raise the temperature for stainless steel. Hence, less energy is required to raise the temperature which allows stainless steel to heat up faster as compared to water. This will cause burnt chocolate. Therefore, the most appropriate way is to go through double boiling as the water would heat up slowly for the chocolate to melt, without the chocolate getting burnt. ]]> 2022-04-23 06:47:26 UTC https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2154404395 charmaine https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2154418093 Double boiling allow us to melt chocolate using indirect heat (steam) rather than direct heat from a stove or radiation from a microwave.

Hence, as the water is boiling, the chocolate would melt.

However, compared to using a stainless steel pan, which has a specific heat of 0.5, the pan would heat up way faster than the chocolate as lesser energy is required, which may lead to the burning of the chocolate. ]]> 2022-04-23 07:41:12 UTC https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2154422202 joei https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2154446023 The specific heat capacity of stainless steel is very low, at 0.500 as compared to water, which has a specific heat capacity of 4.184. This would mean that stainless steel does not require as much energy to heat up, and would thus heat up very fast, burning the chocolate. For water, since it requires more energy to heat up, it is a more gentle way of melting the chocolate using non-direct heat. Using double boiling, the chances of the chocolate being burnt is lesser.

Water has a specific heat capacity of 4.184J/g.K which means it will take a while for the water to reach a rolling boil and for steam to form and make contact with the bottom of the stainless steel bowl. The stainless steel bowl has a specific heat capacity of 0.5ooJ/g.K which means it gains heat relatively quickly causing the chocolate to melt quickly. Combining these 2 factors, this allows the user to control the heat so that the chocolate does not burn so easily as chocolate is heat sensative and is susceptible to burning and it also prevents browning as the chocolate is melting under an indirect heat source.]]> 2022-04-23 09:23:23 UTC https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2154461130 Nickson Chia https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2154481694 Since chocolate has a specific heat capacity of 3.9 J/g°C which is higher than stainless steel at 0.5 J/g°C, if the chocolate were to be directly heated by an open flame, the temperature of the stainless steel bowl would heat up significantly faster which can cause the chocolate to burn easily.

( Experimental and numerical evaluation of the effect of micro-aeration on the thermal properties of chocolate, 2022) We can infer that liquid chocolate has a higher specific heat capacity than the steel pan of 0.5 J/gk but a lower specific heat capacity than water of 4.184 J/gK. Since chocolate is sensitive to heat, we will avoid direct heating of chocolate from the steel pan as the steel pan heats up very quickly. This might cause the chocolate that is in direct contact with the pan to burn.
Therefore, double boiling method is used where we have a pot of boiling water that heats up slower than chocolate acting as an intermediate. This will thus prevent the chocolate from burning.

This means that stainless steel gets heated up faster than water as the amount of energy required to raise the temperature of stainless steel is lesser.

Thus, if chocolate is heated directly on a stainless steel pot, it will burn quickly. A more appropriate way to melt the chocolate is double boiling, which heats the chocolate through indirect heating, using steam from the water. More energy is needed to heat up the water as it has a higher specific capacity, so it will take longer for the water to be heated up. The steam comes into contact with the bowl and this heats up the chocolate gently, preventing the chocolate from burning. This gives the melted chocolate a smoother texture.

This sudden increase in heat will burnt the bar, thus is it not an appropriate way.

With double boiling, the stainless steel pot will be heated up first, followed by water and then the chocolate bar. Since water has a higher specific heat capacity than the bar, the amount of heat energy transferred from the boiling water to the bar will ensure that the bar is able to melt slowly over a gentle heat and for a better temperature control. This ensures even melting of the bar and hence a more appropriate method. ]]> 2022-04-24 07:37:15 UTC https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2155089875 jing wen https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2155133892 we can compare 2 methods of melting chocolate. one, using a stainless steel pot to melt it under fire, second, double boiling where a bowl of chocolate is being placed above a pot of boiling water to melt. since the specific heat capacity for water is the highest (4.184) as compared to stainless steel (0.500), this shows that water is able to raise the temperature of chocolate at a slower rate as compared to stainless steel. this will allow the chocolate to be melted at a gentler way and will have a lower risk of burning the chocolate as compared to using a stainless steel pot]]> 2022-04-24 09:18:21 UTC https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2155133892 Malcolm 02 https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2155159450 Double boiling chocolate is the preferred mehtod because you would have maximum control over the heating process. Double boiling uses the steam of the barely simmering water to melt the chocolate. Using a stainless steel pot to simmer some water and placing another steel bowl on it.

Since stainless steel has a much lower specific heat capacity, less energy is needed to heat up the steel pot. Hence heating up the pot much faster than needed, burning the chocolate and making it thick and gloppy.

But by placing another bowl onto the stainless steel pot with water. Which has a higher specific heat capacity, the water would heat up much slower and convert into steam, tranferring its heat energy to the bottom of the pot and therefore not burn the chocolate but gently melt the chocolate to produce a smooth and silky texture.

The metal pots used when melting the chocolates have a low specific heat capaciy. Thus, the amount of energy needed to increase its temperature by 1 degree celsius is very little and it heats up quickly. Using the double boiling method, the pot comes into direct contact with steam which is the gaseous form of water. Water has high specific heat capacity and thus ensure a more even, slower and less intense heating of the chocolates, preventing them from getting burnt. ]]> 2022-04-24 10:12:33 UTC https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2155160735 Malcolm Mak 03 https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2155186420 Because in this instance the water acts as a moderator, between the heating of the stainless steel.

This is because the specific heat capacity of water 4.184 J/g. K and the specific heat capacity of chocolate is 3.9J/g. K. Double boiling slows down the amount of time it takes to heat up, having more control over the heat, whereas direct heating from the stove can quickly heat up the chocolate and affect the flavor and texture of the chocolate. ]]> 2022-04-27 12:00:47 UTC https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2160234001 chloe 01 https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2160283953 Chocolate has a specific heat capacity of 3.9 J/g.K. When melted directly on a stainless steel pan, which has a specific heat capacity of 0.500 J/g.K, this would result in the pan heating up much faster than the chocolate, thus resulting in it burning rather than melting.

Water has a specific heat capacity of 4.184 J/g.K, thus requiring more energy for it to boil. This results in a gradual rise in temperature, allowing steam to form. steam is a much gentler heat source, which would allow the chocolate to melt slowly, thus reducing the chances of it burning.

The specific heat of the chocolate was 3.9 J/g. k, which is less than the specific heat of water. This means that the stainless steel will get heated up very quickly and the chocolate will be melted very quickly which might even get burned. However, it takes longer for water to heat up which exposes long duration of heat to the chocolate. This indirect heat helps to heat and melt the chocolate more gradually, which greatly reduces the risk of overheating the chocolate.]]> 2022-04-27 13:01:30 UTC https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2160321592 keaya 01 :) https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2160411908 there is a need to double boil chocolate to melt it in order to prevent the chocolate from getting burnt. the specific heat capacity of stainless steel pans is 0.500 (J/g.K) which means that the stainless steel pan will gain heat faster resulting in a quick rise in temperature causing the chocolate to burn more easily. when chocolate is placed on double boiler, the water with a specific heat capacity of 2.000 (J/g.K) will be heated at a slower rate and will take a longer while to increase in temp hence preventing the choco from getting burnt.]]> 2022-04-27 13:50:45 UTC https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2160411908 Sean lim 02 https://padlet.com/matthew_koh/j0bqzz7p9e175b30/wish/2160432338 Due to the water present in the chocolate having a high specific heat capacity, another container (usually glass bowl) is used to slowly transfer the heat.

Its low heat capacity as compared to water, which has a specific heat capacity of 4.184 J/g.k, means that stainless steel requires significantly lesser energy and lesser time to heat it up to a specific temperature to melt the chocolate. As stainless steel heats up very quickly, it is difficult to control how fast it takes to heat it up. On the other hand, using water via the double boiling method, will not cause the chocolate to burn. This is because due to its higher specific heat capacity, the water will take a longer time to heat up. thus allowing the chocolate to melt slowly and evenly due to the heat transferred from the water being at a more slower and even rate.

Since steam is used to boil the chocolate instead of the direct heat from the pan. If the pan was used to burn, the limitations of the stainless steel heat capacity value will burn the chocolate, which is 0.5 J/g.k. However, water has a heat capacity value of 4.184 J/ g.k.
