Work & Heat Transfer
With regards the following question:
A cylinder fitted with a piston has a volume of 0.1 m3 and contains 0.5 kg of steam at
0.4 MPa. Heat is transferred to the steam until the temperature is 300 °C, as a result
the volume increases to three times and the change in internal energy is 680.1 kJ.
Determine the work and heat transfer for this process. Neglect the change in kinetic
and potential energies.
Is work found by using W = P x Delta V = 400 x (0.3-0.1) = 80kJ
or is it more involved than this?
