An Ideal gas at a Pressure of $1-4$MPa and temperature of $$360$C$)$ is expanded adiabati cally to apressure of $100$ Kpa, the gas is then heated at constant volume until it attains $360$ gagain, when its Pressure is found to be $220$ Kpa and finally it is compressed is thermally unfil its original Pressure of $1-4$ Mpa is altaned.Draw P$-$V diagram for there proceses and if the gas has amass of $0,23$ kg findsa $-$ the Value of $8-$b$-$ the change of internal energy during the adiabatic process$-$Take Cp for the gas $1\mathrm{.}005$ KJ$/$KgK
