Question

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? (1 point)
the scientist is investigating charless law, which shows that temperature and volume are directly proportional.
the scientist is investigating boyles law, which shows that pressure and volume are directly proportional.
the scientist is investigating charless law, which shows that temperature and volume are inversely proportional.
the scientist is investigating boyles law, which shows that pressure and volume are inversely proportional.

Explanation:

Charles's law states that for a given mass of gas at constant pressure, the volume is directly proportional to the temperature. When gas particles move faster, temperature increases and volume (balloon expanding) increases too. Boyle's law is about pressure - volume inverse - proportionality at constant temperature. Here, the situation fits Charles's law.

Answer:

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