Assertion(A): If volume of a gas is increasing but temperature of the gas is decreasing, then heat given to the gas may be positive, negative or zero.
Reason(R): Heat given to a gas is a state function. It is not path function.
Reason(R): Heat given to a gas is a state function. It is not path function.
View answer and explanation
Correct option: C
If Assertion is correct but Reason is incorrect.
The Assertion is correct because the heat given to the gas depends on the path taken (first law of thermodynamics). The Reason is incorrect because heat is a path function, not a state function.
