One mole of an ideal gas in a closed system undergoes a mechanically reversible adiabatic compression process and changes from V1= 0.05 m^3 and P1= 1 bar to P2= 12 bar. Calculate Q, W, ∆U, and ∆H of the process. If the process will become irreversible with 50% efficiency, calculate the W, Q, ∆U, and ∆H.

An ideal gas initially at 600K and 10 bar undergoes a four-step mechanically reversible cycle in a closed system. In step 12 (the process that changes the system from State 1 to State 2), pressure decreases isothermally to 3bar; in step 23, pressure decreases at constant volume to 2bar; in step 34 volume decreases at constant pressure; and in step 41, the gas returns adiabatically to its initial state. Take Cp=(7/2)R and Cv=(5/2)R. Determine the efficiency of the cycle. (Hint:...

The ideal Otto cycle, shown in the figure above, is the cycle used by gasoline engines to generate useful work. It consists of an adiabatic compression from step 1 to 2, followed by an isochoric increase in pressure from step 2 to 3, followed by an adiabatic expansion from 3 to 4, and finally an isochoric decrease in pressure from step 4 to 1.Consider an Otto cycle that works on a monoatomic ideal gas (γ= 5/3,cV= 3R/2), initially at a...
