1. The problem statement, all variables and given/known data

Complete this table for H20:

2. Relevant equations

T, °C...........P, kPa..................h, kJ/kg...........x Phase..........description
200 ................................................................0.7
140...........................................1800
....................95...............................................0.0
80.................500
....................800.....................3162.2

I just need help getting started, all I have is a packet full of tables and I dont know which to use and when, if someone could give me some general information on solving this type of questions so I can do other ones by myself it would be much appreciated.

I know that were supposed to find 2 intensive properties to start but then I dont know what to do since there a lot of tables. Does anyone know how to do this?

You just have to match up the values. If you have a phase it will be in the saturated tables, high pressures in compressed liquid tables, and high temperatures in superheated vapor tables. If you can't find the numbers on the tables then you have to use interpolation.
