Assertion (A): According to kinetic theory of gases the internal energy of a given sample of an ideal gas is only kinetic.
Reason (R): The ideal gas molecules exert force on each other only when they collide.
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
Solution:
For an ideal gas, internal energy is purely kinetic due to random motion, so (A) is true. Ideal gas molecules have no intermolecular forces, so (R) is false. Thus, (A) is true and (R) is false.
