suggest a method to liquefy atmospheric gases
Hey Mohith,
There are various methods to liquefy atmospheric gases, I have listed a few below,
The main principle behind this concept is
the forces of attraction between the particles and the heat required to overcome these
.
Basically the atmospheric gases exists as liquids at very low temperatures such as -150 °C or - 200°C. In order to liquefy such gases by cooling is practically very difficult. Only a few gases are cooled to liquefy them.
To liquefy a gas we need to bring the gas molecules together very close to each other. This is achieved by compressing them using high pressures. At very high pressures, the boiling point of the liquid rises. So at practically achievable temperatures, the gases can liquefy and exist as liquids.
This principle is mainly used to liquefy gases such as oxygen, hydrogen, helium, nitrogen, and petroleum gas too. The LPG cylinder contains liquefied petroleum gas at high pressure.
Hope this helps.
All the best.!!
