Thorium's boiling point of 4788 °C is the fifth-highest among all the elements with known boiling points. [b] The properties of thorium vary widely depending on the degree of impurities in the sample. The major impurity is usually thorium dioxide ThO 2); even the purest thorium specimens usually contain about a tenth of a per cent of the ...
The following list has substances known to be gases, but with an unknown boiling point. Fluoroamine; Trifluoromethyl trifluoroethyl trioxide CF 3 OOOCF 2 CF 3 boils between 10 and 20° [142] Bis-trifluoromethyl carbonate boils between −10 and +10° [37] possibly +12, freezing −60° [143]
It is also notable for having one of the largest liquid ranges for a metal, and for having (unlike mercury) a low vapor pressure at high temperatures. Gallium's boiling point, 2676 K, is nearly nine times higher than its melting point on the absolute scale, the greatest ratio between melting point and boiling point of any element.
There is a strong correlation between higher sodium intake and higher blood pressure. [96] Studies have found that lowering sodium intake by 2 g per day tends to lower systolic blood pressure by about two to four mm Hg. [97] It has been estimated that such a decrease in sodium intake would lead to 9–17% fewer cases of hypertension. [97]

The element with the lowest boiling point is helium. Both the boiling points of rhenium and tungsten exceed 5000 K at standard pressure; because it is difficult to measure extreme temperatures precisely without bias, both have been cited in the literature as having the higher boiling point. [11]
