Two amazing, firstly to see such incredibly interesting science and secondly to hear such an incredibly boring person. Although to be fair his English is way better than my German.

Reminds me of how water can be superheated in a microwave or on a stove; I do the latter every time I make pasta. 8-)

#7 I had to watch it several times. Watch 0:49 thru 3:35 again, the light blue lines on the graph (Pcr and Tcr) intersect @ 1:29 by adding heat and pressure and that Critical Point happens at 3:06 (where the different phases/characteristics (water,gas,vapor) mesh and the visual differences disappear. After 3:35, by reducing heat and pressure, the 3 phases (water, gas, vapor) reappear.

That's how I understand it. The graph is constant for all substances, but the heat and pressure will differ for each type of substance.

Pretty cool.
