How do you turn the nitrogen in the air into liquid form

May 01 2006Answers Best Answer The boiling Point of Nitrogen (temperature in which it changes from liquid to gas) is -195 8 degrees celsius Hence to convert nitrogen in the air (70%) you have to pass the air through a compressor to reduce pressure (a lot) This works because of the physics equation PV=kT (P = pressure V= volume T=temperature Get price


Guidelines for the Safe Use of Liquid Nitrogen

Liquid nitrogen is nitrogen in a liquid state at a very low temperature It is a cryogenic fluid that causes rapid freezing on contact with living tissue Since the liquid to gas expansion ratio of nitrogen is 1 694 at 20 degrees Celsius a tremendous amount of force can be generated if liquid nitrogen is rapidly vaporized In addition Get price
