Question

What is the effect of pressure on change od state of matter class9?

Answer 1

The increase in pressure changes the state of matter from gas to liquid and also from liquid to solid. But increase in pressure alone cannot change the state of matter. Every gases and liquid have certain temperature above which the application of pressure would not change the state of matter.

Answer 2

Explanation:

By increasing pressure, particles of matter can be brought close together. When we apply pressure on a gas enclosed in a cylinder, it starts compressing and converts into liquid. Thus, by applying pressure and reducing temperature a gas can be liquefied.
