Cooking a chemical or physical change?

Answer 1

Both of those processes are parts of cooking. It depends on what you're doing.

If you're melting or freezing its a physical change. If you're changing it into

another substance then its chemical.

A chemical change is when a substance is changed into another entirely

different substance. This happens when an event occurs that changes the

composition of the substance. Examples of chemical changes are color

changes, absorbing energy, releasing energy, odor changes, producing gases,

producing solids, and can't be easily reversed.

A physical change is when there is a change is physical properties. This

happens when an event occurs that doesn't change their chemical. Examples

of physical changes are changes in the texture, shape, size, color, odor,

volume, mass, weight, and density.

Answer 2

Cooking is an example of chemical change because the complex biochemicals that make up the food are chemically changed by the heat of cooking. Cooking causes chemical reactions that effect permanent changes in the food that is being cooked. (Food cannot be "uncooked" after cooking.)

The changes that result from cooking are chemical ones. There are chemicals in cooked food that were not there before cooking, and there were chemicals there before cooking that are not there after cooking. Chemical changes have occurred.

Answer 3

Cooking is a chemical change.
