Phase Transition Example
A container having a volume of 2 m3 contains .05
m3 of saturated liquid water and 1.95 m3 of
saturated vapor at 0.15 MPa. (a) Determine the
amount of heat transfer in order to vaporize all
the liquid water in the container. (b) What is
the final pressure (at the saturated vapor
condition). (c ) What is the quality at the
initial state. (Neglect losses)

Saturated liquid line
Transition from 1 a mixture of liquid and vapor
to 2 100 saturated vapor. It should follow
the green line since the volume and the mass both
are constants during this process.
