When ice melts and becomes a liquid it is a physical change. When the liquid boils and becomes gaseous it is a physical change. It is a chemical change when the molecular structure has been changed in some way, here it has not.

When a substance changes state is it a physical or a chemical change?
It undergoes a physical change... IE: ice and steam have the same chemical makeup (H20). To undergo a chemical change, the substance has to interact with something else. However, this can be a trick question because if something is heated in a real world setting then it could possible react with oxygen, nitrogen, carbon dioxide, or another trace gas in air.
