Sense 1
Meaning:
Nitrogen in a liquid state
Classified under:
Hypernyms ("liquid nitrogen" is a kind of...):
atomic number 7; N; nitrogen (a common nonmetallic element that is normally a colorless odorless tasteless inert diatomic gas; constitutes 78 percent of the atmosphere by volume; a constituent of all living tissues)
cryogen (a liquid that boils at below -160 C and is used as a refrigerant)
Context examples:
Electron microscopy involving an aqueous suspension of a sample which is applied in an extremely thin film to a grid, frozen in liquid nitrogen and maintained in this state by means of a special mount.
(Cryo-Electron Microscopy, NCI Thesaurus)
It is designed so that the liquid nitrogen is absorbed into retention medium that surrounds the samples and maintains them at liquid nitrogen temperatures.
(Dry Shipper, NCI Thesaurus)
Even localized warming would have been enough to turn the liquid nitrogen into vapor, cause it to expand quickly and blow out a crater.
(New Models Suggest Titan Lakes Are Explosion Craters, NASA)
The new, alternative models for some of the smaller lakes (tens of miles across) turns that theory upside down: It proposes pockets of liquid nitrogen in Titan's crust warmed, turning into explosive gas that blew out craters, which then filled with liquid methane.
