Problem $04\mathrm{.}008-$ A piston$-$cylinder device with stops

A piston$-$cylinder device with a set of stops initially contains $0\mathrm{.}400$ kg of steam at $1\mathrm{.}0$ MPa and $400C.$ The location of the stops corresponds to $40\%$ of the initial volume. Now the steam is cooled. Use steam tables.

Problem $04\mathrm{.}008.$c $-$ Final temperature

Determine the temperature at the final state in part $b.$

The temperature at the final state is $C.$
