E.35 Two moles of an ideal gas initially at a pressure of 150KPa and at a temperature of 20 ° C are subjected to a quasi-static expansion to a volume double of their initial volume. Determine the work done and the variation of internal energy knowing that the trigger is: (a) isothermal; (b) adiabatic. We give |y = 1,4 et Cy = 20,9 J/(mol·K).
