Why does liquid nitrogen not freeze your hand?

They freeze to the point they shatter when struck. Since the temperature of liquid nitrogen ranges from -210oC to -195.8oC (-346oF to -320.44oF), a human hand seems boiling hot in comparison – which explains why it wouldn’t freeze immediately.

How can nitrogen be liquefied?

Liquid nitrogen is generated by cryogenic or reversed Stirling engine coolers that liquefy the main component of air, nitrogen (N 2). The cooler can be powered by electricity or through direct mechanical work from hydro or wind turbines. Liquid nitrogen is distributed and stored in insulated containers.
