NEET Physics Heat Engines Assertion Reason Question
Assertion (A): In a heat engine operating at constant pressure, the change in enthalpy represents the heat absorbed by the system.
Reason (R): Enthalpy is a state function and independent of the path taken between initial and final states.
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 a heat engine at constant pressure, enthalpy change (ΔH) equals the heat absorbed (qp), and as a state function, enthalpy is path-independent.
