Temperature is the property of a body which is proportional to the ____.

A.

total kinetic energy of its molecules

B.

average kinetic energy of its molecules

C.

average speed of its molecules

D.

maximum speed of its molecules

Correct answer is B

The last postulate of the kinetic molecular theory states that the average kinetic energy of a gas particle depends only on the temperature of the gas. Thus, the average kinetic energy of the gas particles increases as the gas becomes warmer
