I got all of them except for part c Could you please explain

I got all of them except for part c. Could you please explain how you determine what phase it is and what table you used to get that phase?

The system is made of H2O. Given the following data, determine the phase of the system.(Check with Thermodynamic Tables)

a) T = 170 oC, p = 6.8 bar

b) T = 155oC, p = 5 bar

c) T = -10oC, p = 1 bar

d) T = 200 oC, p = 2.8MPa

Solution

C).

At 1 bar and 0 c water will be in solid state.since it\'s freezing temperature is zero degree Celsius.but given temperature is less than zero degree Celsius.hence water Will be in solid state.
