A $0\mathrm{.}400m^3$ closed rigid vessel contains a two$-$phase mixture of steam at $200\mathrm{.}0C.$ The vapor occupies $86\mathrm{.}00\%$ of the total

volume $($State $1).$

Determine the quality of the two phase mixture at State $1.$

quality:

Now, the vessel is heated to a temperature of $250\mathrm{.}0C($State $2).$ What is the phase at State $2?$

subcooled liquid

two$-$phase mixture

superheated vapor

cannot be determined from the information given

What is the heat interaction term for the state change $(kJ)?$

heat interaction term:
