CHEMICAL
Chemical energy is stored in the bonds between atoms. This stored energy is released and absorbed when bonds are broken and new bonds are formed - chemical reactions. Chemical reactions change the way atoms are arranged. These reactions both absorb and release energy, but the net reaction releases energy.

No, changes in state of matter (such as melting, freezing, boiling) are physical changes, not chemical changes. Chemical changes involve the formation of new substances with different chemical properties.
There are no physical changes. there are only chemical changes.
Do Oreos undertake any chemical changes? Yes. How can Oreo be a chemical changes? Cooking involve chemical reactions, modifications of chemical molecules.
Physical changes are changes that affect the form of a chemical substance, such as changes in state or shape, without changing its chemical composition. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties. Physical changes are usually reversible, while chemical changes are often irreversible.
physical or chemical changes
some chemical changes can be reversed but they are hard to reverse usually
chemical changes
Cooking food can cause chemical Changes
Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
