In this question, you want to know how can we separate nitrogen from the air? this method is the main method of preparation of nitrogen.
00:15
So if you want to prepare nitrogen, you will prepare it from the air, which is the air considered the high source for the nitrogen.
00:26
So what happened is, we bring the air that is a mechanism, sure of gases and cool it so the cooling must be blue negative one one one hundred ninety six leases when we make blue cooling the blue system richard we found the air become now in the liquid form then we started to make warming so by warming that's mean increasing that temperature when we increase it in temperature we found that the nitrogen will vaporize first before the oxygen why because the nitrogen gas become boiling at negative 196 slidious while oxygen is boiling at negative 1, 83 slasias.

So the nitrogen started boiling out.
01:48
Then we make for these gases that contain of nitrogen, we make beautification.

Bureification because still there are with nitrogen...
