Required information

A piston$-$cylinder device initially contains $0\mathrm{.}50$ kg of steam at $3\mathrm{.}5$ MPa $,$ superheated by $7\mathrm{.}4C.$ Now the steam loses heat to

the surroundings and the piston moves down, hitting a set of stops at which point the cylinder contains saturated liquid

water. The cooling continues until the cylinder contains water at $200C.$

Determine the final pressure and the quality $($if mixture$).$

The final pressure is

$|$kPa$.$

The quality of the mixture is
