Answer :
Answer:
The solid-liquid line in the water phase diagram has a negative slope, whereas for most other substances it has a positive slope.
The ice has a lower density as compared to water still they have in the solid phase.
Reason how the solid-liquid line in the phase diagram as compared to other:
In the solid-liquid line in the water phase diagram it contains the negative slope. While the most other substance should have the positive slope.
Also, when the pressure is applied so the higher density should be favored. In the water, the highest density phase should be likely the liquid water.
