Problem $2\mathrm{.}2$

A closed rigid container of volume $0\mathrm{.}5m^3$ is placed on a hot plate. Initially, the container holds a two$-$phase

mixture of saturated liquid water and saturated liquid vapour at $P_1=100$kPa with a quality of $0\mathrm{.}5.$ After

heating, the pressure in the container is $150$kPa. Indicate the initial and final states on a T$-v$ diagram, and

determine each of the following:

a$)$ the temperature, in $C,$ at each state.

b$)$ the mass of vapour at each state.

c$)$ If heating continued, determine the pressure when the container holds only vapour.
