Assertion: A heat engine is the reverse of a refrigerator. Reason : A

1.	Assertion: A heat engine is the reverse of a refrigerator. Reason : A refrigerator cannnot work without some external work done on the systemA. If both assetion and reason are true and reaasons is the correct expanation of assetionB. If both assetion and reason are tur but reason is not the correct explanation of assetionC. If assertion is true but reason is falseD. If both assertion and reason are false.
Answer» Correct Answer - A In a heat engine heat connot be fully converted to work and a refrigerator cannot work without some external work done on the system.
