Sugar!!!!!

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.

Ice is an reversible change this means that if we heat it turns to water and if we froze it it turns back to ice

# data[].attributes.body
A physical change of food is when the food changes form but not its chemical identity.

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

Chemical change is when u added new substances in food and your changing the entire thing.

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

# data[].attributes.body
Physical change is when the appearance of the food changes like the texture or shape and no new substances are added into the food.

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.

What is a chemical change

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 changes in food:

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

# data[].attributes.body
Physical change:

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.

A physical change is when food is cut, chopped, freezed, or warmed for example butter

# data[].attributes.body
Physical Change

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.

# data[].attributes.body
Physical Change:

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.

# data[].attributes.body
Physical Change: A Physical Change is when there's a change in the appearance of a food or a substance without changing its molecular/chemical structure. An example would be cutting an apple

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.

# data[].attributes.body
Physical change is a type of change where the physical properties of matter change boiling water is a example of an physical change

Definition of physical change:

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

Physical change

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

Chemical change:

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

What is a physical change?

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.

Chemical Change

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

I have learned that physical change is is when something physical changes in its appearance

Chemical change when something changes from the inside

# data[].attributes.body
So basically what i learned is that physical change is the change of the physical properties without altering or changing its chemical properties, chemical change changes its chemical properties and while creating a new substance, for example burning wood, it creates an oder and also creates a new substance which is ash

a chemical change is when a food change is shape substance and color it just not change its shape it change everything of it. example is when u bake a cake so the egg, sugar, bread and etc... change completely into one thing.

# data[].attributes.body
A chemical change is the exact opposite of a physical change. It is altered in shape,texture, and color, and its chemical composition also changes, thus creating a new substance. For example, when you bake a cake, the batter reacts to the heat to make a chemical reaction and rise. In other words, the cake hits a growth spurt :D.

A chemical change is a process in which one or more substances are transformed into entirely new substances with different chemical properties. This change is usually irreversible under normal conditions and involves the breaking and forming of chemical bonds. Chemical changes result in the production of new materials with different compositions and characteristics from the original substances. EZ

A physical change is when the look or structure of the food or thing like for example an ice cube when its frozen its hard and when it melts its soft. On the other hand a chemical change is when the material that the food is made of is changed and there are a few ways you can tell its a chemical change like the way it smells or looks

My understanding of physical and chemical changes

# data[].attributes.body
I think that a physical change is when the matter only changes its form and no new substance is created, while chemical changes are when the food changes completely and a new substance is created, you can know if a change is a chemical change if the food changes color or if there is a odor that wasn't there before.

# data[].attributes.body
A physical change is a change that occurs in food that alters its shape and texture, but does not change its chemical composition. In other words, no new substance is created. For example, If you cut an onion in half, it is split in half, but it is still an onion (although it will make you cry a lot :D)

a physical change is color , you see when you cook a steak its color changes from pink to brown because of oil

# data[].attributes.body
A physical change is that change in the form or appearance of a substance with no change in its chemical composition. This means the substance retains its original properties and can often be reversed. Such changes do not produce new substances; they simply modify the way the substance looks or behaves. For example water, water is a physical change because you can melt it then you can freeze it , its obviously reversible

# data[].attributes.body
Basically physical change is when you cook or bake how the food changes in appearances an example is that when you cook chicken it doesn't look like how a chicken would actually look if it was alive so it was physically changing

A chemical change is when cooking properties or/and food are changed chemically. For example, if you take the cow that you brutally slaughtered, then you deep fry it, the cows nutrients could be sucked out by the cooking oil. PLEASE DO NOT SLAUGHTER COWS WITHOUT PERMISSION.
