An increase in the temperature of a gas means more energetic molecules, so a larger volume is needed to accommodate the same amount of gas. 4. If a gas cools, the molecules within it have less kinetic energy (motions) and can therefore be packed into a smaller volume. The gas has a higher density and will tend to sink.

Answer:

When Heated

both its vapor pressure and the volume it occupies increase.

When Cooled

the molecules within it have less kinetic energy (motions) and can therefore be packed into a smaller volume.
