Heat energy flows from a body at ____ temperature to a body at _____ temperature.

Assertion : It is not possible for a system, unaided by an external agency to transfer heat from a body at lower temperature to another body at higher temperature. Reason : According to Clausius statement, “ No process is possible whose sole result is the transfer of heat from a cooled object to a hotter object

Assertion : First law of thermodynamics does not forbid flow of heat from lower temperature to higher temperature. Reason : Heat supplied to a system always equal to the increase in its internal energy.
