Each of three identical 15.0-L gas cylinders contains 7.50 mol of gas at 295 K.Cylinder A contains Ar,cylinder B contains Cl₂,and cylinder C contains N₂.According to the kinetic molecular theory,which gas has the highest average kinetic energy? A)Ar B)Cl₂ C)N₂ D)All have identical average kinetic energies

Question

Quizplus · Accepted Answer

According to the kinetic molecular theory, the average kinetic energy of a gas is directly proportional to its temperature and does not depend on the identity of the gas particles. Since all three cylinders are at the same temperature, they have the same average kinetic energy. Therefore, the answer is D.
