(2) 17 mole of ideal gas is initially at a pressure of P0 and temperature of To. It then undergoes a thermal cycle with the following thermal processes consequentially. (i) Increase pressure to P1 isothermally, P1>Po; (ii) Temperature decreased to To.-AT at constant volume, AT>0; (iii) Temperature increased to T 0 at constant pressure. (a) Sketch all the paths of the thermal processes (i), (ii) and (iii); and the corresponding P chrves; (b) Find the internal energy changes, heat and work done for the states after completing processes (i), and (ii) and (iii). Express your answer in terms of 11, P0, P1, To, ATand the gas constant R
