Suggest a method to liquefy atmospheric gases. 


Atmospheric gases can be liquified by 

  • Increasing pressure 
  • Decreasing temperature 

When the atmospheric gases are compressed under high pressure , the particles of the gas come closer. Due to this, the space between the particles decreases. 

After applying a certain pressure, the particles of gases start attracting each other, resulting in the formation of a liquid.

When the change of state from gaseous to liquid takes place, a lot of heat is released. 

Hence, to take away this heat released during the process, the temperature is also decreased.
