Tina fills two balloons with an equal amount of helium gas. She puts one balloon in the freezer and, after twenty minutes, takes it out. She observes that this balloon is smaller than the one that remained at room temperature. The balloons are shown below.

Tina can accurately explain the difference in the size of her balloons by saying:

She explains that an increase in temperature causes the volume of helium gas to expand.

This explanation is based on Charles's Law, which states that the volume of a gas is directly proportional to its temperature when pressure is held constant. Therefore, the balloon that was kept at room temperature has a larger volume because the helium gas inside it is warmer compared to the gas in the balloon that was cooled in the freezer, which has a reduced volume due to the lower temperature.
