Question

state one nessecary condition to liquify gases.(other than applying high pressure)​

Answer 1

Answer:

Liquefying a gas means conversion of gas into liquid.

The two necessary conditions for liquification of gases are:

1. By increasing the pressure

2. By reducing the temperature.

For example:

1. When a high pressure is applied to a gas, it gets compressed and when we lower it's temperature it gets cooled.

2. Ammonia gas can be liquefied by applying high pressure and lowering temperature.
