A gas in the initial state of P1 = 75 psia and V1 = 5 ft.3 undergoes a process to P2 = 25 psia and V2 = 9.68 ft.3, during which the enthalpy decreases 62 BTU. The specific heat at constant volume is cy = 0.754 BTU/lb.°R. Determine (a) the change of internal energy, (b) the specific heat at constant pressure, (c) the gas constant R.
