Webb29 maj 2024 · Helium is the only substance that remains liquid and does not solidify at 0 K under atmospheric pressure. To solidify helium, high pressures of about P = 29 bar at below 1.73 K are required. Its critical point is at a pressure of P c.p . = 2.27 bar and T c.p . = 5.2 K. At atmospheric pressure below about 4.2 K helium becomes a liquid, denoted He I. WebbHelium physical properties Fourteen isotopes are now recognized. 258Md has a half-life of 2 months. This isotope has been produced by the bombardment of an isotope of einsteinium with ions of helium. Eventually enough 258Md should be made to determine its physical properties.
