1. A cylinder fitted with a piston has a volume of \( 0.2 \mathrm{~m}^{3} \) and contains 0.8 kg of saturated (liquid and vapor) steam at 0.6 MPa . Heat is transferred to the steam until the volume has doubled. During this expansion process the pressure remains constant. Determine the work done, the final temperature of the steam and the heat transferred to/from the steam. Assume that this process is quasi-static.
