so, i have specific volume of 50 m^3/kg from the steam table and do interpolation to find the temperature and pressure correspond to the specific volume of 50 m^3/kg?

specific volume should be 50m^3/kg. so i should be find the temperature and pressure from the steam table?

Mass and volume are given. I just have no clue about what its about when it just evaporated. Volume should be constant since it is a rigid tank.

It should be at the superheated vapour state since it state the water is just evaporated.

everything i know is stated up there.

Well, the volume is constant.
