Asssertion: It is not possible for a system, unaided by an external agency to transfer heat from a body at lower temp. to another at a higher temp.
Reason: It is not possible to violate the second law of thermodynamics.

A

If both assertion and reason are true and reason is the correct explanation of assertion

B

If the assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false

Text Solution

Verified by Experts

The correct Answer is:
A
Second law of thermodynamics can be explained with the help of example of refrigerator, as we know that refregerator , the working substance extracts heat from colder body and rejects a large amount of heat to a hotter body with the help of an external agency i.e. the electric supply of the refrigerator. No refrigerator can ever work without external supply of electric energy to it.
