In the cycle shown in the figure, (1) 1.00 mol of an ideal diatomic gas is initially at a pressure of 1.00 atm and a temperature of 0.0°C. (2) The gas is heated at constant volume to T2 = 145°C, and (3) is then expanded adiabatically until its pressure is again 1.00 atm. It is then compressed at constant pressure back to its original state. P, atm Adiabatic V, V,L (a) Find the temperature after the adiabatic expansion. 97 °C (b) Find the heat absorbed or released by the system during each step. Q1-2 = X kJ Q2-3 = 0 V kJ Q3-1 = X kJ (c) Find the efficiency of this cycle. X % (d) Find the efficiency of a Carnot cycle operating between the temperature extremes of this cycle. X %
