B)number of moles of the gas increases.
C)temperature of the gas decreases.
D)volume of the container decreases.

Question

Quizplus · Accepted Answer

According to the kinetic molecular theory, the pressure of a gas is directly proportional to the average kinetic energy of its molecules. This means that as the temperature of the gas decreases, the average kinetic energy of its molecules also decreases, resulting in a lower pressure. Therefore, option C is the best choice as it describes a decrease in temperature leading to a decrease in pressure. The other options do not describe a direct relationship between pressure and the given variable.
