Q:

The Kinetic energy of gas molecules

A) is unaffected by temperature variations	B) decreases with increase of temperature
C) increases with decrease of temperature	D) increases with increase of temperature

Answer & Explanation Answer: D) increases with increase of temperature

Explanation:

Kinetic Energy $K . E = \frac{1}{2} m V^{2}$ or

$K . E \propto V^{2}$ , Where 'm' is the mass and 'v' is the velocity of molecules.

Velocity is proportional to temperature. Hence, KE is proportional to temperature and would increase with temperature.
