    Choose the incorrect statement from the following

    $S1:$ The efficiency of a heat engine can be $1,$ but the coefficient of performance of a refrigerator can never be infinity.

    $S2:$ The first law of  thermodynamics is basically the principle of conservation of energy.

    $S3:$ The  second law of thermodynamics does not allow several phenomena consistent  with the first law. 

    $S4:$ A process,whose only result is to transfer heat from a colder to a hotter object, is  impossible.
