Thermodynamics: Determine the State/Phase using Tables

Learn how to use tables when answering thermodynamics questions!

1. What state is water in at a pressure of 600kPa and a specific volume of .3 m 3 /kg. Find its specific
internal energy value.

2. What state is ammonia in at a temperature of 100℃ and a specific volume of 1.2065 m 3 /kg. Find
its specific internal energy value.
3. What state is propane in at a temperature of 20℃ and pressure of 10 bar. Find its specific
internal energy value.
4. What state is water in at a temperature of 282℃ and a specific volume of .01 m 3 /kg. Find its
specific internal energy value.
5. What state is water in at a pressure of 140kPa and a temperature of 320℃. Find its specific
internal energy value.
