In the P-V diagram (Fig 15.14.1) given below, three thermodynamic processes occur for an ideal gas. Processes `1 to 2, 2 to 3 and 3 to 1` are isothermal, isochoric and adiabatic processes respectively. The total amt of work done is 10 J. During the process `3 to 1,` 20 J of work is done on the system. The amount of heat added to the system during the process ` 1 to 2` is
