In an experiment involving a balloon, a scientist notices that the gas particles within the balloon begin to move faster, resulting in the balloon expanding. Which statement best describes the experiment?

Question

A. The scientist is investigating Boyle's law, which shows that pressure and volume are inversely proportional
B. The scientist is investigating Boyle's law, which shows that pressure and volume are directly proportional
C. The scientist is investigating Charles's law which shows that temperature and volume are directly proportional
D. The scientist is investigating Charles's law, which shows that temperature and volume are inversely proportional

Answer 1

The correct statement that best describes the experiment is:

C. The scientist is investigating Charles's law which shows that temperature and volume are directly proportional.

Charles's law states that at constant pressure, the volume of a gas is directly proportional to its absolute temperature. As the gas particles in the balloon move faster (indicating an increase in temperature), the volume of the balloon expands.
