C) the speed of the gas molecules will increase.
D) All of the above statements are correct.

Question

Quizplus · Accepted Answer

When the temperature of a fixed amount of an ideal gas is increased, the kinetic energy of the gas molecules also increases. This leads to an increase in the average speed of the gas molecules, as described by the Maxwell-Boltzmann distribution. The pressure and volume of the gas may change as a result of this increase in temperature, but this is not necessarily true in all situations. Therefore, choice C is the best answer.
