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/

I used to work with supercritical fluids. Turns out it was just a phasse I was going through.

"Because I have nowhere else to put it"

The video, his hair, and the fluid in the chamber are all at equilibrium in this video. That was awesome!

@jagara1 You misunderstand. I don't care if you understand it. I learned surface tension in high school and while the math is complex, I didn't have problems understanding it. Its not my problem that you don't get it.

@DubIDubblix You said - "The surface tension disappears. I have no degree and was able to grasp it." - I just skimmed through the wiki on surface tension and am most impressed that you understand this area given the molecular and mathematical complexity of surface tension. It does not answer how when surface tension disappears that a liquid will flow up vertically though.I don't think you understand the slightest thing about this area which is why you have fobbed me off with visiting the wiki

@jagara1 Hahahaha. I'm not your teacher nor do I owe you anything. Be proactive and go find the answers yourself. You're already signed into Google, try going to their homepage and typing in your question.

[jagara1]

@DubIDubblix I asked two questions and you are completely unwilling/unable to answer either of them!

[jagara1]

@DubIDubblix What a frickin' copout!

[DubIDubblix]

@jagara1 You need to do some reading to understand surface tension. No one here knows how much you do or do not know already nor could we explain it to you without that knowledge. Hell, Wikipedia should have a long article that can answer your questions.

[jagara1]

@DubIDubblix Thank you so much for your explanation!

Can you please now explain what surface tension is?

Why when surface tension present a liquid behaves the way it does and why when it is not present the liquid behaves differently?

"Seeing something happen" is a whole order of magnitude in difference to understanding and being able to explain why it happens!

[DubIDubblix]

@jagara1 The surface tension disappears. I have no degree and was able to grasp it. You can see it happen.

[Slampropp]

@jagara1 I don't understand the process either ( I have a degree in nothing,) but that's hardly relevant. The fact that it's something novel that you don't usually see fluids doing "should" be enough to pique your interest (if you're into these sorts of things.)
