A piston cylinder assembly has 0.5 m3 of nitrogen gasa t 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 PV diagram of the
process.
