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.
Correct Answer
