a carnot engine containing $1$ mole of ideal gas is initially at rest at $600$k and $5$ atm. it goes through the following series of processes to make one cycle: $1.$ Isothermal expansion to $5$ times its initial volume $2.$ Adiabatic expansion to a pressure of $0\mathrm{.}2$ atm $3.$ Isothermal compression to a volume of $26$ lt and pressure of $0\mathrm{.}99$ atm $4.$ Adiabatic compression to the inital volume, pressure and temperature Calculate the PVT values at each state and changes in internal energy, heat and work transfers during each of the processes. Also calculate the efficiency of this engine
