Gas Heat

A sample of gas is held at constant pressure. If the Kelvin temperature of this gas sample increases what happens to the average kinetic energy and volume?

• average KE decreases and volume decreases

• average KE decreases and volume increases

• average KE increases and volume decreases

• average KE increases and volume increases

Two balloons are filled with the same amount of helium gas. Balloon #1 is placed in the freezer. After 20 minutes, balloon #1 is removed from the freezer and compared to balloon #2 that stayed in a room temperature environment. What did the individual likely observe about the two balloons?

• Balloon #1 was smaller in size because the pressure increased.

• Balloon #1 was smaller in size because the pressure decreased.

• Balloon #1 was larger in size because the pressure increased.

• Balloon #1 was larger in size because the pressure decreased.

What does the graph show?

• The volume and temperature of the gas are not related.

• As the pressure of a gas increases, its volume decreases.

• If the temperature of a gas doubles then its volume will also double.

• As the volume of gas increases, its temperature decereases.
