Using the phase diagram for H2O, which of the following correctly describes water at 0°C and 1 atm?

1 Answer

Answer :

At the melting point(Explanation) if you look at the phase diagram and look at the point where the water is 0 degrees C and 1 atm, they meet right on the line. This is the line that shows the melting point of this substance. Therefore, since the point is on the line, water at 0 degrees C and 1 atm is at the melting point.
