This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately. Blue type items have an article available by ...
Upon freezing, the volume of mercury decreases by 3.59% and its density changes from 13.69 g/cm 3 when liquid to 14.184 g/cm 3 when solid. The coefficient of volume expansion is 181.59 × 10 −6 at 0 °C, 181.71 × 10 −6 at 20 °C and 182.50 × 10 −6 at 100 °C (per °C). Solid mercury is malleable and ductile, and can be cut with a knife ...

Helium remains liquid down to absolute zero at atmospheric pressure, but it freezes at high pressure. Solid helium requires a temperature of 1–1.5 K (about −272 °C or −457 °F) at about 25 bar (2.5 MPa) of pressure. [107] It is often hard to distinguish solid from liquid helium since the refractive index of the two phases are nearly the ...
Water boiling at 99.3 °C (210.8 °F) at 215 m (705 ft) elevation. The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid [1] [2] and the liquid changes into a vapor.
It is a very soft, whitish-grey solid in the alkali metal group, similar to potassium and caesium. [9] Rubidium is the first alkali metal in the group to have a density higher than water . On Earth, natural rubidium comprises two isotopes : 72% is a stable isotope 85 Rb, and 28% is slightly radioactive 87 Rb, with a half-life of 48.8 billion ...
