A piston–cylinder assembly contains 0.9 kg of air at a temperature of 300 K and a pressure of 1 bar. The air is
compressed to a state where the temperature is 470K and the pressure is 6 bar. During the compression, there is
a heat transfer from the air to the surroundings equal to 20 kJ. Determine the work during the process in kJ, Plot
the process in PV diagram.

Explanation:
A piston-cylinder assembly contains 0.9kg of air at a temperature of 300K and a pressure of 1 bar. THe air compressed to a state where the temperature is 470K and the pressure is 6 ba. During the compression there is a geat transfer from the air to the surroundings equal to 20kJ. Using the ideal gas model for air, determine the work during the process in kJ?
