Physical Science Class Review

Terry fills two balloons with the same amount of helium gas. She places one of her helium balloons in the freezer.

After twenty minutes, she removes the balloon from the freezer and notices that it is smaller than the balloon that

stayed at room temperature. Her balloons are shown above.

How does Terry correctly explain the difference in

the size her balloons?

• She says that an increase in pressure increases

  the volume of helium gas.

• She says that a decrease in pressure decreases

  the volume of helium gas.

• She says that a decrease in temperature

  increases the volume of helium gas.

• She says that an increase in temperature increase the volume of the helium gas.
