NEET Physics Heat Engines Assertion Reason Question

Type: Assertion Reason-assertion-Medium-Class 11

Assertion (A): For an ideal gas under isothermal conditions, the internal energy change is zero. | Reason (R): In isothermal processes, the temperature of the system remains constant, leading to no change in internal energy.

A

Both A and R are true and R is the correct explanation of A.

B

Both A and R are true but R is not the correct explanation of A.

C

A is true but R is false.

D

A is false.
