A closed ideal gas system undergoes a quasistatic thermodynamic process during which its temperature remains fixed. How does its enthalpy vary in this process?
Homework Answers
Enthalpy remains constant because for ideal gas enthalpy in function of only temperature so if temperatur is constant then enthalpy remains constant. i.e. ΔH=Cp(T2-T1), if T1=T2, then ΔH=0.

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.
