The initial pressure and temperature of 1 mole of an ideal gas are 1 MPa and 380 K respectively. It is heated at constant pressure till the temperature is doubled and then is allowed to expand reversibly and adiabatically till the temperature is reduced to 380 K as shown in Figure 1.4, find the heat transferred and work interaction. If it is required to restore the system from final state to the original state by a reversible isothermal path, determine the amount of work to be done on the system.
