One mole of an ideal gas, initially at 30 [°C] and 1 [bar], is changed to 130 [°C] and 10 [bar] by two different mechanically reversible processes: • The gas is first heated at constant volume until its temperature is 130 [°C], then it is compressed isothermallyuntil its pressure is 10 [bar].• The gas is first compressed adiabatically; then it is heated isobarically to 130 [°C] and 10 [bar]. Calculate Q, W, ΔU, and ΔH in [J] for each case. Take Cp = 5/2R and Cv = 3/2R.
One mole of an ideal gas, initially at 20 °C (293.15 K) and 1.50 bar, undergoes the following mechanically reversible changes. It is compressed isothermally to a point such that when it is heated at constant volume to 100 °C (373.15 K) its final pressure is 10 bar. Take Cp = (7/2)R and Cv = (5/2)R. Hints: Process 1 to 2: T1 = T2; Process 2 to 3: (P2/T2) = (P3/T3), thus (P2/T1) = (P3/T3) Use equations for isothermic and isochoric processes. Wtotal = W12 + W23 and Qtotal = Q12 + Q23. What is the change in internal energy? What is the change in enthalpy?

An ideal gas is undergoing a mechanically reversible process consisting of four steps: (1->2) adiabatic compression from Vi=0.1 m3, Pl=1 bar to V2, P2=5 bar (2->3) isobaric expansion at P2=5 bar until a temperature T3=80 'C is reached. (3->4) isothermal expansion until a pressure of P4=3.5 bar is reached. (4->1) isochoric process to return to Pi, V, . Calculate Q, W, AU, AH for each branch and for the complete cycle. y=Cp/Cv=7R/5R Draw this process on a pressure vs. Volume diagram and carefully label all points. Be systematic, show all your work.
The state of an ideal gas with C_P = (5/2)R is changed from P1 = 1 bar and V1=12 m3 to P2=12 bar and V2=1 m3 by the following mechanically reversible processes: (a) Isothermal compression. (b) Adiabatic compression followed by cooling at constant pressure. (c) Adiabatic compression followed by cooling at constant volume. (d) Heating at constant volume followed by cooling at constant pressure. (e) Cooling at constant pressure followed by heating at constant volume. Calculate Q, W, ΔU, and ΔH for each of these processes, and sketch the paths of all processes on a single PV diagram.

An ideal gas, initially at 30°C and 100 kPa, undergoes the following cyclic processes in a closed system: (a) In mechanically reversible processes, it is first compressed adiabatically to 500 kPa, then cooled at a constant pressure of 500 kPa to 30°C, and finally expanded isothermally to its original state. (b) The cycle traverses exactly the same changes of state, but each step is irreversible with an efficiency of 80% compared with the corresponding mechanically reversible process. Note: The initial step can no longer be adiabatic. Calculate Q, W, ∆U, and ∆H for each step of the process and for the cycle. Take CP = (7/2)R and CV = (5/2)R.
