It will melt. It will boil. It will harden. It will evaporate.
I gave my students this multiple choice question: Which will most likely happen to a solid substance that is heated?

Only one answer is correct among these 4 choices:
- It will melt.
- It will boil.
- It will harden.
- It will evaporate.

Could you tell me which one is correct?

It will melt.
