Deposition is the phase transition in which gas transforms into solid … WebHelium can be solid, just not at Earth sea level pressure. Every element (or technically any substance if you wanted) can have a phase diagram showing the state it will enter at a given temperature and pressure. Helium just so happens to stay fluid as close to absolute zero as we can get at standard pressure. Basically, even at absolute zero ...
WebMay 23, 2005 · Lets say 1atm, everything is solid at 0K except Helium which is still merrily a liquid. My thoughts are currently along the lines that He doesn't form molecules (like Hydrogen) so it is left to interact with other He particles only via Van der Waals forces. At 0k the atoms in the (now liquid) helium have no kinetic energy. WebThe temperature at which the solid–liquid phase change occurs. Boiling point The temperature at which the liquid–gas phase change occurs. Sublimation The transition of a substance directly from the solid to the gas phase without passing through a liquid phase.
