Do we need energy to cool a body, if yes, what happens when i cool a body to very low temp and placed contact with the body which has temp about 40-50 degree celcius, does the energy travels from cool body to high body or something else? I think the heat,water,current moves from high potential to low potential objects. In the same way the heat transfer from high potential i.e cool body to low potential i.e high body. Right! But when i verified with HCV VOL-2 it gave that the heat always travels from hot body to cool body, Is it right, If yes can i have the explanation plz. And remember im from 9th class and preparing IIT in sri chaitanya IPL campus, which is one of the best school in India. out of which narayana co spark is my old school so better you tell me the correct answers PLZ
