Question

formation of ice is a __________ chemical change physical change

Explanation:

Physical change involves a change in the state of matter without altering its chemical composition. When water freezes to form ice, only the state changes from liquid to solid. The chemical formula of water (\(H_2O\)) remains the same before and after freezing. In a chemical change, new substances are formed with different chemical properties. Since no new chemical substance is formed during ice formation, it is not a chemical change.

Answer:

physical change
