A heat engine containing 2.50L of an ideal monoatomic gas at 310.15 K, 1.00 atm (Cp,m =5/2 R) is designed to go through the following cycle:%3DAB; A 2-fold decrease in pressure under constant volume conditions.B>C; Isothermal expansion to increase the volume by 4-fold.C→D; Reversible adiabatic compression to the initial pressure.D→A; Constant pressure compression back to the initial volume.Will the first step occur spontaneously if the temperature of the surroundings isheld at -50.0 °C?

B Question 11 of 14 View Policies Current Attempt in Progress Step 1 Determine p2, in lb./in². A rigid, well-insulated tank contains a two-phase mixture of ammonia with 0.0022 ft3 of saturated liquid and 1.5 ft3 of saturated vapor, initially at p₁ = 50 lbf/in². A paddle wheel stirs the mixture until only saturated vapor at higher pressure, p2, remains in the tank. Kinetic and potential energy effects are negligible. Determine the pressure p2, in lb/in², and the amount of energy transfer by work, in Btu. P2 = i Save for Later lbf/in² -/1 Attempts: 0 of 4 used ||| Step 2 The parts of this question must be completed in order. This part will be available when you complete the part above. : Submit Answer
