A piston-cylinder device has a volume of 0.1 cubic meters and contains 0.5kg of steam at 0.4 MPa. Heat is transferred to the steam until the temperature is 300 degrees Celsius, while the pressure remains constant. Determine the heat transfer for this process in kilojoules.
(My professor told us to use steam tables not the ideal gas law. Not sure how to do this.)
