In a phase diagram that I have attached, the line marked in between ice and water (yellow and blue) is the conditions in which solid (ice) and liquid (Water) can coexist. As the graph shows, solid ice and liquid water coexist most when the temperature is zero, which should make sense since ice melts at 0, and water freezes as well at 0 degrees celsius.
