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.

Answer 1

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

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

This is based on the principles of gas behavior outlined in Charles's Law, which states that, at constant pressure, the volume of a gas is directly proportional to its temperature. In the freezer, the temperature of the helium gas decreased, causing the volume of the gas to contract, resulting in the balloon appearing smaller compared to the one at room temperature.
