D)The volume of the particles is negligible compared to the volume of the gas.

Question

Quizplus · Accepted Answer

Charles' Law states that at a constant pressure, the volume of a gas is directly proportional to its temperature in Kelvin. This is explained by the kinetic molecular theory assumption that the average kinetic energy of gas particles is proportional to the Kelvin temperature. As the temperature of a gas increases, the particles move faster, resulting in more collisions with the container walls and an increase in volume. Therefore, choice A is the most frequently cited assumption to explain Charles' Law.
