Extracted text: Nitrogen with a mass of 2.5 kg expands at a constant pressure. The initial pressure and temperature in the piston cylinder system is 170 kPa and 27 °C, respectively. Because of the heat transfer, the system reached a final temperature of 200 °C. Note R= 0.2968 kJ/kgK Determine: a. The heat required b. The work c. The change of enthalpy d. The change of internal energy
