NEET Physics Question - Thermal Physics

Assertion (A): Internal energy of an ideal gas \( U = nC_V T \) is due to random motion of gas molecules.

Reason (R): A container is moving with speed \( v \). It is suddenly stopped by a force, temperature of gas increases.

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:

Assertion (A) is true as internal energy comes from random molecular motion. Reason (R) is also true, as kinetic energy converts to internal energy upon sudden stopping. However, (R) does not explain (A).
