Low kinetic energy.

Front

What is compression in terms of volume and pressure?

Back

Compression is the reduction of volume of matter as a result of applied pressure.

Front

What happens to the kinetic energy of a substance when heat is removed?

Back

The kinetic energy decreases.

Front

What is the relationship between temperature and the motion of particles in a substance?

Back

As temperature increases, the motion of particles increases.

Front

What is contraction in terms of volume?

Back

Contraction is the decrease in volume of matter due to a decrease in temperature.

Front

How does pressure affect the volume of gases?

Back

Increasing pressure on a gas decreases its volume.
