It becomes a gas. It becomes a solid. It gets new atomic bonds. It gets destroyed.
I gave my students this multiple choice question: A student places a pan of water on the stove. What happens to some of the water as it is heated to a boil?

Only one answer is correct among these 4 choices:
- It becomes a gas.
- It becomes a solid.
- It gets new atomic bonds.
- It gets destroyed.

Could you tell me which one is correct?

It becomes a gas.
