Why is food darkening a chemical change?
This darkening involve chemical reactions.
What is the chemical change taking place when food is cooked?
Cooking food involves chemical changes like new substances are made, process is irreversible, and an energy occurs. An example is cooking with baking powder, the sodium hydrogencarbonate breaks down when heated and releases carbon dioxide.
Is cooking food is a reversible change?
No, cooking food is not a reversible change. During cooking, chemical reactions occur that alter the food's composition, texture, and flavor, making it impossible to revert to its original state. For example, proteins denature and starches gelatinize, resulting in changes that cannot be undone. Thus, once food is cooked, it cannot be transformed back into its raw form.

Is water boiling in a pan a physical or chemical change?
It depends on what is boiling. If you are boiling WATER, then it is NOT a chemical change, it is a physical change (change of state from liquid to gas).

Cooking a chemical or physical change?
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.
