4. A piston cylinder assembly has 0.5 m³ of nitrogen gas at 0.4 MPa and 300 K. If the electric resistance is used to heat the cylinder by passing a current of 1 A for 10 minutes from a 120 V source. This process leads to expand nitrogen at constant pressure with a heat loss of 2.8 kJ. Calculate the final temperature of nitrogen. Draw a neat schematic sketch and (35 Points) PV diagram of the process.
