One mole of a monoatomic ideal gas initially has a volume of 24.4L at latm and 298K undergoes a cyclic process as shown in Figure 6. Process 2→3 is an adiabatic expansion and process 3→1 is an isothermal compression. Given the V3 = 138L and T2 = 596K 2 1 3 Volume Figure 6 Calculate (a) the internal energy change in the process 1→2 (b) the entropy change in the process 1→2 Pressure

6. A heat engine consists of the cycle p shown for 3 moles of an ideal 2p monatomic gas. It starts at point 1 with pressure p and volume V; it goes via an isochoric (constant 1 volume) process from point 1 to 3 point 2 until the pressure doubles; it then goes from point 2 to point 3 via an adiabatic process; finally it goes V from point 3 to point 1 via an isothermal process. А. I What is the volume of the gas at point 3? Express your answer in terms of V (the volume of the gas at point 1). В. What are W12, W23, and W31? Express your answer in terms of p, V. 2.

Is this the correct way to solve for W(ca)

Any help with doublechecking my work would be great!
