a A gas is compressed isothermally at 400K from 0 3Mpa to 4Mpa is then cooled isobarically to 290K After that it is expanded adiabatically to 0 9 Mpa Later expanded at constant temperature to the initial value of pressure Finally heated isobarically to 400K Draw the PV diagram and calculate the overall work done change in internal energy and heat supplied Data Cp 3 7R and Cv 2 7R
