What happens if you touch liquid nitrogen?

Liquid nitrogen has a boiling temperature of -196°C at atmospheric pressure. Direct contact can freeze the skin causing frostbite and cold burns. … It is often stated that splashes of liquid nitrogen will run off bare skin due to a vapour layer forming between the skin and liquid – this must NEVER be relied upon.

Under what condition is nitrogen in liquid form?

At normal atmospheric pressure, nitrogen is a liquid between 63 K and 77.2 K (-346°F and -320.44°F). Over this temperature range, liquid nitrogen looks much like boiling water. Below 63 K, it freezes into solid nitrogen.

What is the difference between liquid nitrogen and nitrogen gas?

Liquid nitrogen is the nitrogen when it is in its gas phase – cooled and pressurized so much that it becomes liquid. Like carbon dioxide, nitrogen is a gas at standard temperature and pressure, and, like carbon dioxide, it must be pressurized and cooled to change state.
