One cubic meter of an ideal gas at 600 K and 1000 kPa expands to five times its initial volume as follows,
(a) By a mechanically reversible, isothermal process.
(b) By a mechanically reversible, adiabatic process.
(c) By an adiabatic, irreversible process in which expansion is against a restraining pressure of 100 kPa.calculate the final pressure. and take Cp = 21 J/ mol K.
