Physical Change - A physical change is a change to a sample of matter in which some properties of the material change, but the identity of the matter does not. Physical changes can further be classified as reversible or irreversible. The melted ice cube may be refrozen, so melting is a reversible physical change.
Chemical Change - Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.
Melting a traditional snowman involves an increase in temperature which causes the snow, which is water in a solid state to undergo a phase transition to become liquid water. Melting is a physical reaction where this activity demonstrates a chemical reaction.
