A)speed.
B)kinetic energy.
C)both of these
D)none of the above

Question

Quizplus · Accepted Answer

In a gas at constant temperature, all molecules, regardless of their mass, have the same average kinetic energy according to the kinetic theory of gases. This is because the average kinetic energy of gas molecules is directly proportional to the temperature of the gas.
