Question

The usual name for the following State two condition necessary to liquefy gases

Answer 1

Hi friend,

I suppose your question is *What are the conditions to liquefy gases*?

Well, here is your answer :)

There are two conditions necessary for liqueifing gases-

•Pressure
•Temperature

We should increase pressure and decrease pressure to liquefy gases.

By decreasing temperature the kinetic energy of the molecules will decrease and by increasing pressure the molecules will come together and then as the particles came closer the gas is liquefied.

Hope it helps..!!
