Question

How pressure can change the state of matter? Give two conditions with examples.​

Answer 1

Pressure plays a very important role in changing the physical state of matter. By varying the pressure liquids can be changed into solid and gases can be changed into liquid. Gases when subjected to high pressure gets compressed into a small volume and when we lower its temperature it gets liquified.

I hope it will help you.

Have a great day.

Answer 2

Answer:

Increasing or decreasing the pressure can change the state of matter. Applying pressure and reducing temperature can liquefy gases. Solid carbon dioxide (CO2) is stored under high pressure. Solid CO2 gets converted directly to gaseous state on a decrease of pressure without coming into the liquid state.
