Liquid helium Liquid helium At standard pressure, the chemical element helium exists in a liquid form only at the extremely low temperature of −270 °C (about 4 K or −452.2 °F). Its boiling point and critical point depend on which isotope of helium is present: the common isotope helium-4 or the rare isotope helium-3. These are the only two stable isotopes of helium. See the table below for the values of these physical quantities. The density of liquid helium-4 at its boiling point and a pressure of one atmosphere (101.3 kilopascals) is about 0.125 grams per cm, or about 1/8th the density
Boiling Point: Road to Hell Boiling Point: Road to Hell Boiling Point: Road to Hell ("Xenus: Точка кипения", "Xenus: Boiling Point") is a video game developed by the Ukrainian game studio Deep Shadows and published in 2005 by Atari. Boiling Point's gameplay is a combination of open world, FPS, and role-playing video game mechanics. Critical response upon its release was, with few exceptions, lukewarm. This was attributed to the many technical issues that plagued the game's release: bugs, glitches and choppy performance. Patches have been released that address many, but not all, of these deficiencies. Deep Shadows released a successor in 2009 called "", and
