Question

Assertion :When a vessel is heated,the heat is transferred from base to another part,bringing the vessel to uniform temperature.This process is cannot be reversed. Reason: If the process is reversed it will violate the second law of thermodynamics as the part of the vessel will not get cooler spontaneously and warm up at the base.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Assertion

When a vessel is heated,the heat is transferred from base to another part,bringing the vessel to uniform temperature.This process is cannot be reversed.As the heat is lost to the environment hence it can not be brought back hence it can be reversed.

Reason.

If the process is reversed it will violate the second law of thermodynamics as the part of the vessel will not get cooler spontaneously and warm up at the base.As the second law states that entropy of system is always increasing hence,the If process is reversed it will decrease its entropy hence it will violets second law of thermodynamics.

Hence both Assertion and Reason are correct and Reason is the correct explanation for Assertion
