Example:

Making smoothiess

some signs of a chemical change are...

-a new smell

-color change

-produces gas, etc

• Burning of paper and log of wood.

• Digestion of food.

• Boiling an egg.

• Chemical battery usage.

• Electroplating a metal.

• Baking a cake.

• Milk is going sour.

of a physical change is ice melting when it melts it can its still ice but liquid

Chemical change when something changes from the inside

When the ingredients go under a transformation at molecular level resulting in a new substance also is not reversible

Example: When we bake a cake the batter (which has all the ingredients)undergoes a transformation due to the batter reacting with the heat and causes the cake to rise

Chemical change is when you cook or cut something in a way that the chemical properties change like for example when you fry an egg the amount that were there originially are destroyed because as we know frying things isn't good for our health

A physical change is a change when the state or the look changes. No new substance is created. For example cutting paper. Whenever you cut paper the paper is still paper it’s not anything new just the look has changed.

When Ingredients or microscopic qualities join with each other and create a new substance which is a sole determinator of chemical change.

Food Digestion:

When a Human or any being with a stomach eats food it digests the food through the process of breaking the food down to tiny pieces then mixing the food with enzymes which makes it easy to digest

KHAQAN

Physical change is when a food changes from it’s original from.

Example

Bread when you bite into it changes it shape and is no in it’s original shape anymore

AbdulBari

Physical change is a change in the state of matter so if something just changes it shape then its physical change

Example:

Freezing water: when you freeze water it turns into ice but it is still water. the shape just changes

Rotting is a chemical change because the bonds in the food changes making rotten food chemically different from the original food.

A chemical change is when some thing changes chemically like when a cake rises due to the mix of all the food.

Chemical Change: A Chemical Change is when there's a change in the molecular/chemical structure in the food. An example would be baking a cake.

Physical change is when you cook or cut something in a way that only the appearance changes and the chemical properties remain the same for example when you cut vegetables only the physical appearance changes.

When the appearance of the matter changes but not the molecular level. This includes chopping,

cutting, heating(sometimes), freezing(sometimes)

Example: When we chop up fruits the fruits stay the same, only the appearance or size changes into smaller pieces.

Physical change is when tiny particles or food ingredients or microscopic qualities go through change that affects they way it might look, feel, or even the colour which might make it seem odd

Example:

When dissolving sugar in water they don't mix and become one substance the qualities of the sugar stay the same and so do the qualities of water.

KHAQAN

Chemical changes are when new substances are formed and the chemical structure actually changes and they are mostly irreversible

Physical changes in food :

The physical form of the food is actually changed but not the real food itself or it’s chemical structure or molecules

Chemical change e.g: Baking a cake

Physical change e.g: chopping of vegetables

A chemical change is a change when the whole product or food changes. It’s when new substances are created with different properties. For example caramelising sugar. That’s when sugar turns into caramel when you heat the sugar. That’s a chemical change because a new substance is created. There is also proof of it because the sugar changes Color.

Chemical change is a change in what something is made of. One example would be souring milk

Chemical change is when the substance is change and it forms and new substance

Example

The ingredients undergo chemical reactions to produce new substances, such as carbon dioxide gas, which makes the cake rise.

Example : Melting ice is an example of physical change because no new substances are added and it melted because ice needs a cold area to stay in its shape.

Example : An example is popcorn because you have to add oil and salt and kennel to make a salty delicious popcorn.

For example melting ice . The ice turns into liquid and if we freeze it it becomes solid

Chemical change is when new substances are formed

For example when meat is heated beyond it's usual temperature

Author : Aliana

When a new substance is created by the mixture of substances

Serotonin and Dopamine:

Serotonin and Dopamine dont litteraly mix in the brain but they keep a balance beetween complete deppresion and overwhelming joy. They influence each other based on the stimuli provided by the brain stem

KHAQAN

Popcorn is a chemical change because you have to add new substances in the popcorn like salt and oil. It also changes shape.

It’s a chemical change because, Making yogurt is considered a chemical change because it involves the transformation of substances at the molecular level. The process of making yogurt relies on the fermentation of milk, which results in new chemical compounds and the development of different properties.

Dissolving salt in water it is a chemical change because the ingredients change and it has affect on the food of texture and taste

The reason it's a physical change because one when you blend the fruit it physically changes.

It was a phyisical change since the butter freezing is something that can be undone and neither did it change anything in the butter’s mass.

KHAQAN

This is a chemical change because of the lemon acting as an acid and breaking down the protein.

It’s a physical change because the liquid turns fluffy and increases in volume and no chemical changes happen

The experiment I did was mixing cocoa and milk. It is a physical change because the cocoa dissolves inside of the milk.

Caramelising sugar is a chemical because when you put the sugar on a hot pan and burn the sugar. The sugar starts turning into caramel. There is also proof of this that the Color has also changed. So the sugar is not sugar anymore.

By kubra not zaim

Chemical Change: Chemical Change is a process in which the food's chemical structure is altered, resulting in the formation of new substances. An example is the heat caramelizes the sugar in the marshmallow, and the proteins and sugars react, changing the color and texture.
