You would need a container vessel of liquid nitrogen, a means of converting the liquid nitrogen to vapor, and a gas system controlled by regulators. This would be excessively expensive compared to a system of …

The liquid nitrogen spray cooling system consisted of high-pressure nitrogen, a liquid nitrogen dewar, pipes, and nozzles. First, liquid nitrogen was pressurized using high-pressure nitrogen. The liquid nitrogen flowed into valve 5, which was used for controlling and adjusting the initial flow.

Liquid nitrogen also has a large expansion ratio on evaporation - one litre of liquid nitrogen can result in about 700 litres of gas - so only a relatively small volume of liquid nitrogen has to ...

Ideal Gas Law and the Shrinking balloon in liquid nitrogen. Applying the ideal gas law to the gas above the liquid nitrogen in a vacuum flask suggests that the volume of a balloon placed in it would reduce to one-fourth its volume. Actually, it reduces much more than that - virtually removing all the gas in the balloon.

Nitrogen constitutes 78% of the atmosphere and is a constituent of all living tissues. Under normal conditions, nitrogen is a colorless, odorless and tasteless inert gas which has no toxic properties and is slightly lighter than air. As a liquid at -320 ºF it has a water-white appearance and must be handled with care due to its low temperature.

Th e liquid is converted to gas on-site, which saves in transportation costs. One tanker of liquid helium is equiva-lent to six trailers of gaseous helium. Nitrogen Like oxygen, nitrogen is produced by air separation. Liquid nitrogen is provided from Orlando, Fla., in 6,000-gallon mobile tankers. Liquid nitrogen is not used on board the shuttle.

Liquid nitrogen has posed as an alternative, but past reports indicate the cryogen cools at rates roughly 50 times slower than those of ethane, which wouldn't be fast enough to convert water into a glassy sheet. Undeterred, Thorne and colleagues have been experimenting with vitrifying cryo-EM samples using boiling liquid nitrogen.
