Supercritical fluids

Is it a liquid? Is it a gas? Professor Martyn Poliakoff demonstrates supercritical fluids in his office at the University of Nottingham. More with Professor Poliakoff at http://www.test-tube.org.uk/

You are literally too stupid to insult

Go troll somewhere else please.

Actually CO2 is slightly poisonous and its toxicity depends on concentration regardless of amount of oxygen. Although CO2 is more dangerous as asphyxiant gas (displacing oxygen in environment). Concentration of CO2 above 4% even with normal oxygen concentrations can trigger hypercapnia or effects of CO2 poisoning.

No doubt that you are pretty stupid. Not only do you give stupid comments here, from your channel I can see you are one of those crazy Illuminati conspiracy theorists also.

But on a small scale the inside will become super critical and will

cause cooler co2 to move to the middle were it is not super critical

like a Ranque-Hilsch vortex tube.

I... I... what? I can't understand this level of stupidity/ignorance.

[Josh Townsend]

if you conducted this demonstration on a large enough scale would it produce lightening from the frichtion of the gas rising and the droplets falling?

[Sarge Rho]

That's hypoxia, not CO2 poisoning.

[Keghn Feem]

If you put a tiny sealed drum inside and was spun like a car tire and it had

a small hole one side and a axle on the other to spin it. Would a phase bounder form

from hole to the spinning inside tangent edge be formed?

A gas to super critical from the centrifugal force. The inside would have fin to help the gas get moving.

That's a small dream of mine I wish was easier to make come true. >.<

[Brandon Swetland]

I'm fascinated! I wish I was over there to work with Professor Poliakoff. :(
