Questions and Answers

What happens when a substance is heated?

The atoms/molecules themselves expand in size
The volume of the substance decreases
Energy is transferred from the substance, and the atoms/molecules move slower
Energy is transferred to the substance, and the atoms/molecules move faster (correct)

What is the relationship between temperature and the speed of atoms/molecules?

Faster atoms/molecules result in a lower temperature
Slower atoms/molecules result in a higher temperature
Temperature is a measurement of the average speed of atoms/molecules (correct)
Temperature has no relationship to the speed of atoms/molecules

What happens to the volume of a substance when it is cooled?

The volume increases as the atoms/molecules expand in size
The volume stays the same as the atoms/molecules don't change size
The volume increases as the atoms/molecules move further apart
The volume decreases as the atoms/molecules get closer together (correct)
