Is dry ice liquid nitrogen?
Liquid nitrogen is the colorless, odorless, clear liquefied form of nitrogen with a density of 0.807 g/ml at its boiling point (−195.79 °C (−320 °F)) while dry ice is an opaque solid with a density of 97.5189 lb/ft3 at 78.5 °C (109.3 °F).

On vaporization it expands by a factor of 700; one liter of liquid nitrogen becomes 24.6 cubic feet of nitrogen gas. This can cause explosion of a sealed container, or it can displace oxygen in the room and cause suffocation without warning.
How long can liquid nitrogen stay cold?
If the liquid nitrogen is kept in a perfectly insulated container, then it will remain at that temperature forever.
What do dermatologists use to freeze?
CRYOSURGERY (CRYOTHERAPY) is used frequently by dermatologist to treat many skin problems. Liquid nitrogen is sprayed on to the area of skin freezing it. Light freezing causes a peeling, moderate freezing a blistering and hard freezing a scabbing.

The location of the wart and the thickness of the skin around the wart will determine how long it takes for the blister to form. The blister may be either clear or filled with blood. Sometimes a crust or scab may form instead. After 4 to 7 days, the blister will break, dry up and fall off.

Why is liquid nitrogen so cheap?
Since air is everywhere, it’s pretty cheap. In fact, some people have said making liquid nitrogen is cheaper than making soda pop. We funnel air into a big compressor where it undergoes a lot of pressure. The compressor pushes the molecules, or those building blocks that make up air closer together.
