2. A system containing 3.0 moles of a perfect gas with C.,m=2.5 R is put through the following сycle: Step 1, point A to point B: The gas starts at 4.0 atm and 20.0 L and undergoes isothermal expansion to 50.0 L. Step 2, point B to point C: The gas undergoes adiabatic compression to 30.0 L Step 3, point C to point D: The gas undergoes an isochoric process changing the pressure to 4.0 atm. Step 4, point D to point A: The gas undergoes an isobaric process changing the volume to 20.0 L. a) Sketch the cycle on a P-V diagram and label each step. b) Determine the pressure, volume, and temperature at points A, B, C, and D of this cycle. c) Calculate the work for step 1. d) For each step in the cycle, and for each of the quantities q, w, AU, and AH, state whether the value is positive, negative, or zero.
