Required information

A piston$-$cylinder device with a set of stops initially contains $0\mathrm{.}800$ 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.

Determine the compression work if the final state is $500$ kPa $.($Round the final answer to two decimal places. Include a minus sign if

necessary.$)$

The compression work is

kJ$.$
