How are particles of matter affected with increasing or reducing pressure at a given temperature?

Question

Philoid · Accepted Answer

On increasing pressure:

i. On increasing pressure, particles of matter come closer.

ii. If pressure is increasingly applied on a gas, particles of the gas come more closer and a stage is reached when gas may change into liquid.

iii. If pressure is increasingly applied on a liquid, it will change into liquid

On reducing pressure:

i. On reducing pressure, particles of matter expand.

ii. If reducing pressure is applied on a liquid, it will change into gas.

iii. If reducing pressure is applied on a solid, it will change into liquid.
