A piston-cylindrical device contains 1 kg of air at a temperature of 300 K and a pressure of 100 kPa. Air is compressed to a state where the temperature is 460K and the pressure is 600KPa. during compression there is a heat 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.
