Question

State two conditions necessary to liquidfy a gas

Answer 1

Answer:

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 lowering temperature.

Answer 2

• 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:
• 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 lowering temperature
