Answer

Brief Explanations:

Physical changes involve a change in state or form without altering the chemical composition. When water boils and changes from liquid to vapor, it is still water (H₂O) chemically. Chemical changes result in the formation of new substances with different chemical properties. Since boiling water does not create a new substance, it is a physical change.

Answer:

  1. physical change, because a new substance is not formed
