Closed System Example

In a piston cylinder shown below, at first the piston sits on the lower stoppers. The cylinder had $0,4m^3$ of water at $0\mathrm{.}1$ MPa with a dryness factor of $0,2.$ Then the cylinder is heated and water reaches dry saturated vapor form. The volume of the cylinder when the piston touches the upper stoppers is $0,6m^3.$ The pressure needed to push the piston against atmospheric pressure is $0,3$MPa.

a$.$ what is the final pressure inside the cylinder.

b$.$ calculate the heat and work transfer during this process.
