Problem 4 (+ 3 kg of oxygen is sealed in a rigid container at 150°C and 250 kPa. The gas is heated in a constant volume process until its pressure becomes four times the initial pressure. Given the specific gas constant R = 0.259 kJ/kg.K and the specific heat at constant volume Cv = 0.658 kJ/kg.K. Determine: (a) The change in enthalpy of the gas in KJ. (b) Heat transfer during the process.
