For options G and H; G) High pressure will cause the solid to become liquid.H) High pressure will cause the solid to become liquid.

One of them ought to read 'High pressure will cause the liquid to become solid.'

I believe it is a typographical error.

Answer:

See explanation for details.

Explanation:

For water, the following are true:

In a phase diagram the solid-liquid coexistance line has a negative slope.

The solid is less dense than the liquid.

The molecules are closest in the liquid phase.

High pressure will cause the solid to become liquid

For other substances, the following are true:

In a phase diagram the solid-liquid coexistance line has a positive slope

The solid is more dense than the liquid

High pressure will cause the liquid to become solid
