Quizplus · Accepted Answer

According to the kinetic theory of gases, the average kinetic energy of gas molecules is directly proportional to the absolute temperature. Therefore, if the absolute temperature is doubled, the average kinetic energy of the gas molecules will also double. This can be represented as KE ∝ T or KE/T = Constant. Therefore, if T doubles, KE will also double. Thus, the factor by which KE changes is 2 (option B).
