Question

state the conditions necessary to liquefy gases

Answer 1

THE CONDITIONS ARE;

1)Appling high pressure.

2)Apply high and low temperature.

Liquefying a gas means conversion of gas into liquid. For example: When a high pressure is applied to a gas, it gets compressed and when we lower it's temperature it gets cooled.Ammonia gas can be liquefied by applying high pressure and loweringtemperature.

hope it helps

Answer 2

The Ideal conditions to liquefy a gas is as follows:

1) Decrease the temperature of the gas, and

2) Increase the pressure applied on the gas
