what would liquid oxygen look like? color? smell?

Question

Liquid helium as well? Curiousity got the best of me.

Answer 1

Liquid oxygen has a pale blue color and is strongly paramagnetic; it can be suspended between the poles of a powerful horseshoe magnet. Thought It wouldn't have a smell because it is a liquid in that state and what you would be smelling is regular oxygen given off by the liquid, though I suppose if you have ever smelled pure oxygen it would smell like that.



Liquid oxygen has a boiling point of −183 °C, and anything submerged in this bubble bath of liquid oxygen will become very brittle. I would not advise sticking your nose in it. :)



Liquid Helium is clear when in a liquid state, Also it requires a temperature close to absolute zero(-273.15 Celsius) to be in liquid form (-269 degrees Celsius, about 4 Kelvin or -452.2 degrees Fahrenheit)

Answer 2

Both are odorless (since you can't smell either one as a gas).



LOX is pale blue. Helium is colorless.
