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: Option B
Explanation
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.
