The absolute temperature of an ideal gas is directly proportional to which of the following quantities?
A)the average speed of its molecules
B)the average momentum of its molecules
C)the average kinetic energy of its molecules
D)the mass of its molecules
E)It is proportional to all of the above quantities.

Question

Quizplus · Accepted Answer

The average kinetic energy of its molecules is directly proportional to the absolute temperature of an ideal gas. This is known as the kinetic theory of gases. The other options, such as average speed, momentum, and mass, may indirectly affect the temperature of the gas, but they do not have a direct proportionality.
