How cold is liquid nitrogen vapor
WebLiquid nitrogen is just very cold nitrogen. It is 320 o F below zero (-196 o C). It’s so cold that it freezes anything it touches almost instantly. Also, anything at normal room temperature is so much hotter than liquid nitrogen that the liquid nitrogen boils when it touches something.
