  • wait so is a supercritical fluid an inbetween state between liquid and gas?

  • @Icix1 No, what most people learn in chemistry or physics, is a tristate phase diagram. But at a certain point, with high enough pressure and temperature, the fluid becomes "supercritical". This is a state of matter where the fluid has fluid solvation properties, while having gaseous permeability. A perfect way to extract substances tightly bound where liquids can't go (due to surface tension), but need to be dissolved like in liquid.

  • I am. Pm me with details. Location , price, ect thanks !

  • very helpful demo! gives a good insight to what SCF looks like :)

  • where is this machine and can we work something out as so i can do a SC extraction of medical cannabis ???

  • BM BARNEY BLAIR!

  • For more educational videos like this, please visit our research group's YouTube channel.

  • The effect is called critical opalescence. It is caused by fluctuations in the density of the fluid which causes changes in the way that light passes through the fluid.

  • where does the lighting effects come from? do the light change in any way or is it because the co2 gets passable for light on some point?

    sry for my english hard to ask scientifical questions if you are neighter a native speaker nor educated in physics and chemistry in english :p

  • Very nice. ;D

  • sorry for asking...

    is it all the liquid later turn to vapour at critical point?

    need simple explainantion from anyone... i just learn about supercritical fluid yesterday

  • at super critical fase there is no more differance between gas and liquid. so what you see issnt actualy vapour, it just behaves like it a bit

  • Awesome. We're learning about this right now in AP Chem. You should show the cool down of the CO2. This is the only vid I could find that's high enough quality to actually see whats going on.

  • damm i wish i was in Ap chem, but my math isnt high enough.... so now i have to learn about this throough my own research
