Which statement is not correct?   a. For a closed system, the area below the curve of a process on a P-V diagram shows the absolute value of the work done in that process b. For an ideal gas, the specific heat in constant pressure is always greater than the specific heat in constant volume c. During an isochoric process, no work is being done by or on a closed system d.

Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.
