How cold is liquid nitrogen vapor
WebLiquid nitrogen will expand 696 times as it vaporizes. The expansion ratio of argon is 847:1, hydrogen is 851:1 and oxygen is 862:1. If these liquids vaporize in a sealed container, they can produce enormous pressures … WebLN is produced by compressing and cooling nitrogen gas to a point below its evaporation point of about − 196 °C [− 320 °F]. Typically, LN is injected directly into the mixer without making changes to the mixer itself. LN is injected into the mixer with a lance, which can move in and out of the ready-mix truck using a pneumatic cylinder.
