Question

Which statements below describe the changes that molecules undergo when heat is applied during a phase change? (select all that apply.)?

Answer 1

The heat energy is used to move molecules further apart from each others.

When heat is applied, several phases of change occur , this is also known as a change of state. For example, when heating a liquid to make it a gas, also known as evaporation, you are making the spaces between the molecules even bigger because of the heat it suffered.
