Liquid Nitrogen and Labs
« on: December 24, 2006, 02:23:15 PM »
Hello.

I have a little question about liquid nitrogen and the usage of it in chemical labs. If you work in a lab as a research chemist (inorganic chemistry), do you have access to liquid nitrogen? Sorry for asking, I'm just curious about it because I'd like to be able to work with it some day. I'm just fascinated by it as I've never seen some in person.

Thank you,

- Steve

Synthetic inorganic chemists will use it, organic too. I'm a nuclear chemists and we use it almost everyday to keep our detectors cold.
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

Biochemists use it too, and I'm sure physical chemists use it as well. 

If you're really interested in really, really cold liquids, you should look into low temperature physics.  One of my physics professors worked with liquid helium.  He cools down the helium to a superfluid state which has no friction due to the fact that all of the molecules are in their ground state.
