When ice melts it forms water. Ice and water have very different properties. Why then do we say that melting is a physical change?
A physical change is one which involves changes in the physical properties of a substance such as state, shape, size, and colour etc. No new substances are formed in a physical change. Also the original substance can generally be recovered again in a physical change i.e. most physical changes are reversible. as melting of ice only includes the change in physical properties like state, shape etc. more over no new chemical product is formed(i.e. the chemical properties of both ice and water is same). Therefore it is a physical process.
