Question

A mass of 2.4 kg of air at 150 kPa and 12 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.
