To what physical parameter is the temperature of a thin gas most closely related?
A)average number of collisions per second between molecules
B)pressure of the gas
C)average speed of the molecules
D)mean mass per unit volume, or density, of the gas

Question

Quizplus · Accepted Answer

The temperature of a gas is related to the average kinetic energy of its molecules, which is directly proportional to the average speed of the molecules. Therefore, the temperature of a thin gas is most closely related to the average speed of its molecules.
