Determine the temperature, volume, and quality for one kg water under the following conditions: a. U = 3000 kJ/kg, P = 0.3 MPa

b. U = 2900 kJ/kg, P = 1.7 MPa

c. U = 2500 kJ/kg, P = 0.3 MPa

d. U = 350 kJ/kg, P = 0.03 MPa

Using steam tables, I think I got the values for a, but I am so confused about b-d
