Temperature is the property of a body which is proportional to the ____.
- total kinetic energy of its molecules
-
average kinetic energy of its molecules
- average speed of its molecules
- maximum speed of its molecules
The correct answer is: 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.
