A thermodynamic system contains n = 1.62 mol of an ideal gas with a specific heat capacity of cy = 12.47 J mol K-. The system expands adiabatically against a constant external pressurep ext = 1.23 bar. The initial temperature and pressure of the gas are Tj = 311 Kand p=2.43 bar, respectively. The final pressure is pf = 1.51 bar. Calculate the change in enthalpy AH in the system

Question
U po A thermodynamic system contains n = 1.62 mol of an ideal gas with a specific heat capacity of c y = 12.47 J mol K-. The system expands adiabatically against a constant external pressurep ext = 1.23 bar. The initial temperature and pressure of the gas are T j = 311 K and pi=2.43 bar, respectively. The final pressure is p f = 1.51 bar. Calculate the change in enthalpy AH in the system.
