Question
1kg air at 600 K and at 150 kPa is contained in a closed cylinder with variable volume. Now, 150 kJ
of heat is added to the air inside the cylinder during an ISOTHERMAL process. Please note that
during this process neither the pressure nor the volume of the air inside the cylinder is not constant.
