Question

what is the effect of change of pressure on physical state of matter? Explain with an example of a gas.​

Answer 1

Answer:

IN Case of solid, it will contract or expand

In case of liquid, it will be compressed

In case of gas, high pressure will change it into liquid(liquefaction).

Answer 2

Answer:

As pressure rises, the state of matter shifts from gas to liquid, and then from liquid to solid.

Explanation:

When we add pressure to a gas in a cylinder, it begins to compress and turn into a liquid. A gas can be liquefied by adding pressure and lowering the temperature.

However, just increasing the pressure will not affect the condition of matter. Every gas and liquid has a temperature at which the application of pressure will have no effect on the condition of the substance.

Carbon dioxide, for example, is a gas at normal temperatures and pressures.
