Answer 1

Answer:

To fully ‘show’ the effect of pressure on the state of matter, you need a phase diagram. It shows the state of a material at a range of temperature/pressure conditions. You will be able to see how pressure changes affect the phase by tracing a vertical line (constant temperature) through the diagram.

Let me show you a few snippets from my first-year Chemistry lectures. Here is a phase diagram for a material (I plotted lnP on the y axis so I cold squeeze more range in the axis. You see three phases, now, if you start at point A and raise the pressure to point B, (A and B are at the same temperature) you will see that the phases change at certain pressures from gas to liquid and then to solid.

Answer 2

Answer:

Explanation:

The state or phase of matter depends on its temperature and the surrounding pressure. ... Changing the surrounding pressure changes the temperature at which a material goes from one state to another. The reason is because the molecules causing the pressure inhibit the molecules of the material.
