Based on this, we can say a chemical reaction did occur during the Mixing Substances Investigation. Because a reaction occurred, we will call it the Hot Yellow Gas Reaction. We know it is a reaction because there was a color change, a temperature change, and gas was produced. We can call it the HYG Reaction for short.

Before: 

Hot Yellow Gas Reaction. HYG Reaction for short.

Before:

After:

Lionel was cooking dinner and told his friend, Cristiano that the boiling water was a chemical change because the water was changing from a liquid to a gas.

How should Cristiano respond to his friend?
Make sure you explain why you agree or disagree with Lionel.
