Answer 2

Physical Change is process in which there is a physical change of state of the reactant. It's a reversible process.

Eg: Conversion of water into water vapour on heating .

On heating we can convert water into water vapour and on condensing the water vapour we can convert it back to liquid state.

Chemical Change is a process in which reactant goes through a change in its configuration and a new product is formed. It's an irreversible process.

eg: Formation of water from hydrogen and oxygen.

When water and oxygen combine with a fixed ration they make product which is a new product and H2O has different chemical properties than H2 and O2.
