Answer
Freezing of water to ice and evaporation of water are physical changes because the changes are reversible and the chemical composition of the substance remains the same. No new substance if formed. Only change of state occurs i.e. water (liquid) is converted to ice (solid) in freezing and in evaporation, water (liquid) is changed to vapour (gaseous) state.
