A $0\mathrm{.}3m^3$ rigid vessel initially contains saturated liquid$-$vapor mixture of water at $150C.$ The

water is now heated until it reaches the critical state. Show the process on T$-$v diagram with respect to saturation lines and determine:

a$)$ the mass of the liquid water,

b$)$ the volume occupied by the liquid water at the initial state, and

c$)$ the total heat transfer during this process.
