### Clarification on heat transfer but no temp change

I am conceptually confused on how heat (a form of energy) can be transferred into or out of a system, yet there is no temperature change of that system. I do understand that temperature is the measure of thermal motion, not heat, but still need someone to clarify. Thanks!

The only time I can really think of this is happening is during a phase change. During this time, you can think of there being no temperature change because the heat is being fully used to break bonds to go from solid to liquid or liquid to gas.
