0°C is the melting point of water and 100°C is the boiling point of water]]> 2016-10-24 01:38:03 UTC https://padlet.com/ronaldoyee_161/ectwvxap59x/wish/132587272 Temperature ronaldoyee_161 https://padlet.com/ronaldoyee_161/ectwvxap59x/wish/132587559 A measurement of how hot or cold an object is]]> 2016-10-24 01:40:39 UTC https://padlet.com/ronaldoyee_161/ectwvxap59x/wish/132587559 Conversion of temperature scales ronaldoyee_161 https://padlet.com/ronaldoyee_161/ectwvxap59x/wish/132587627 F = 1.8C + 32
C = K - 273.15
F = 1.8K - 459.67]]> 2016-10-24 01:41:27 UTC https://padlet.com/ronaldoyee_161/ectwvxap59x/wish/132587627 Recall! Thermal Energy Transfer ronaldoyee_161 https://padlet.com/ronaldoyee_161/ectwvxap59x/wish/132589594 Thermal energy transfers from a warm object to a cool object and this transfer stops when both objects have the same temperature
Thermal energy can be transferred by conduction, convection and radiation]]> 2016-10-24 01:59:06 UTC https://padlet.com/ronaldoyee_161/ectwvxap59x/wish/132589594 Law of Conservation of Energy ronaldoyee_161 https://padlet.com/ronaldoyee_161/ectwvxap59x/wish/132589749 When thermal energy transfer stops, 
Thermal energy gained by cool object = Thermal energy lost by warm object
(assuming no energy is lost to the surroundings)]]> 2016-10-24 02:00:34 UTC https://padlet.com/ronaldoyee_161/ectwvxap59x/wish/132589749 Specific Heat Capacity ronaldoyee_161 https://padlet.com/ronaldoyee_161/ectwvxap59x/wish/132942383 The specific heat capacity of a substance is the amount of thermal energy required to heat up 1 kg of the substance by 1°C.  

Thermal Energy Transferred = Mass * Specific Heat Capacity * Change in Temperature

where specific heat capacity is measured in J/kg °C]]> 2016-10-25 09:50:13 UTC https://padlet.com/ronaldoyee_161/ectwvxap59x/wish/132942383 Different materials have different specific heat capacity ronaldoyee_161 https://padlet.com/ronaldoyee_161/ectwvxap59x/wish/132944384 Due to a difference in specific heat capacity in different materials, different substances have different abilities to store energy and as a result, two different substances of equal mass subjected to the same amount of thermal energy will have different temperatures after heated for the same period of time]]> 2016-10-25 10:08:26 UTC https://padlet.com/ronaldoyee_161/ectwvxap59x/wish/132944384 Smaller mass heat up faster ronaldoyee_161 https://padlet.com/ronaldoyee_161/ectwvxap59x/wish/132945528 If two glasses of water with different mass was subjected to the same amount of thermal energy, the glass with lesser water will be heated up faster
Therefore, if you need only a cup of hot water, it is a good idea to just heat up that 1 cup of water rather than filling up the kettle completely.]]> 2016-10-25 10:16:35 UTC https://padlet.com/ronaldoyee_161/ectwvxap59x/wish/132945528 High/low specific heat capacity ronaldoyee_161 https://padlet.com/ronaldoyee_161/ectwvxap59x/wish/134119500 A substance with high specific heat capacity means it is able to store up the energy delivered. Therefore, it takes a longer time for that substance to heat up.]]> 2016-10-31 00:05:28 UTC https://padlet.com/ronaldoyee_161/ectwvxap59x/wish/134119500 Common substances specific heat capacity ronaldoyee_161 https://padlet.com/ronaldoyee_161/ectwvxap59x/wish/134119664 Oil has a lower specific heat capacity compared to water.
Water has a higher specific heat capacity compared to air.]]> 2016-10-31 00:07:53 UTC https://padlet.com/ronaldoyee_161/ectwvxap59x/wish/134119664
