NEET Physics Question - Thermal Physics

Assertion (A): The average translational kinetic energy of the molecules in one mole of all ideal gases, at the same temperature is the same.

Reason (R): The average kinetic energy of one mole of any ideal gas at temperature T is given by \( \frac{3}{2}RT \).

Both (A) & (R) are true and the (R) is the correct explanation of the (A)

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

The average translational kinetic energy per mole for any ideal gas is \( \frac{3}{2}RT \), dependent only on T.

So (A) is true. The formula in (R) represents this average translational kinetic energy per mole. So (R) is true and correctly explains (A).
