I need some help with this question:
A mass of 2.4kg of air at 150 kPa and 12 degrees C is contained in a gas-tight, frictionless piston-cylinder device. The air is now compressed to a final pressure of 600 kPa. During the process heat is transferred from the air such that the temperature inside the cylinder remains constant. Calculate the work input during this process.

Answer: 272 kJ.
