Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): When a glass of hot milk is placed in a room and allowed to cool, its entropy decreases.
Reason (R): Allowing hot object to cool does not violate the second law of thermodynamics.
In the light of the above statements, choose the most appropriate answer from the options given below:
- (A) is true but (R) is false
- (A) is false but (R) is true
- Both (A) and (R) are true and (R) is the correct explanation of (A)
- Both (A) and (R) are true and (R) is not the correct explanation of (A)
Answer
(A) (A) is true but (R) is false
