Which term refers to transformations of matter from one state to another, such as gas to liquid?

Explanation:
Transformations of matter from one state to another are changes of state. When energy moves in or out, particles rearrange and a substance shifts between solid, liquid, and gas. For example, ice turning into liquid water or liquid water becoming steam are changes of state. This label directly describes any process that alters the state, so it fits best. (Phase change is a closely related term, but the wording here emphasizes the general label changes of state rather than a specific technical term.)
