0.3 kg of nitrogen gas at 100 kPa and 40 °C is contained in a cylinder. The piston is moved compressing nitrogen until the pressure becomes 1 MPa and temperature becomes 160°C. The work done during the process is 30 kJ. Calculate the heat transferred from the nitrogen to the surroundings.
cv for nitrogen = 0. 75 kJ/kg K.
