Can a system be heated and its temperature remains constant?

Text Solution

Verified by Experts

Yes, a system can be heated and its temperature remains constant. This would happen when the entire heat supplied to the system is spent up in expansion (i.e.,Working against the surroundings).

    B
    If both assertion and reason are true but reason is not the correct explanation of assertion
    C
    If assertion is true but reason is false
    D
