An ideal gas exists in a state with pressure P 0 ​ volume V 0 ​ .It is isothermally expanded to 4 times of its initial volume ( V 0 ​ ) , then isobarically compressed to its original volume. Finally the system is heated isochorically to bring it to its initial state. The amount of heat exchanged in this process is :
