NEET Physics Isothermal & Adiabatic Processes Assertion Reason Question
Assertion (A): During an isothermal expansion of an ideal gas, the internal energy change is zero. | Reason (R): In an adiabatic process, there is no heat exchange with the surroundings.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
In an isothermal expansion, the temperature remains constant, so the internal energy change is zero. However, this is unrelated to the definition of an adiabatic process, which involves no heat exchange.
