• We are now running on a new, and hopefully much-improved, server. In addition we are also on new forum software. Any move entails a lot of technical details and I suspect we will encounter a few issues as the new server goes live. Please be patient with us. It will be worth it! :) Please help by posting all issues here.

For those that went to public school that might be lacking on the intelligence scale.

Three forms of water, only one form is wet. Seems not just the media are lower than 50 IQ.

Except, of course, when the temperature and pressure increases beyond the critical point, whereupon the liquid and gaseous phases become indistinguishable in what is known as a supercritical fluid. In water, the critical point occurs at around Tc = 647.096 K (373.946 °C), pc = 22.064 MPa (217.75 atm) and ρc = 356 kg/m³.

Tc = Critical Temperature
pc = Critical Pressure
ρc = Critical Density

But you already knew that... Right?

PS: I went to public school. ;)

And truth be told, things are a good deal more complex than that, with not only liquid-vapor states, but sold-vapor and solid-liquid states, as well, given the right combinations of temperature, pressure, and density.
