NEET Physics Heat Engines Assertion Reason Question
Assertion (A): In an isolated system, there is no exchange of energy or matter with the surroundings.
Reason (R): The standard enthalpy of vaporization is the heat required to vaporize one mole of a liquid at constant temperature and pressure.
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.
Correct Answer
Detailed Explanation
The assertion correctly describes an isolated system, while the reason explains the concept of standard enthalpy of vaporization. They are both true but unrelated.
