Answer: physical change
Explanation:
A physical reaction is defined as the reaction in which a change in shape, size takes place. No new substance gets formed in these reactions.
Example: salt dissolves in water, as there is only a change in phase and no new substance is being formed.
A chemical reaction is defined as the reaction in which a change in chemical composition takes place. A new substance is formed in these reactions.
Example: Oxidation of magnesium leads to formation of white magnesium oxide and is a chemical change.
