4 days ago · Many bismuth alloys have low melting points and are found in specialty applications such as solders. Many automatic sprinklers, electric fuses, and safety devices in fire detection and suppression systems contain the eutectic In 19.1 -Cd 5.3 -Pb 22.6 -Sn 8.3 -Bi 44.7 alloy that melts at 47 °C (117 °F) [18] This is a convenient temperature since it is unlikely to be exceeded in normal living conditions.
5 days ago · It has the boiling point of being 117.7 ℃, the density (20 ℃) being 0.8109g/cm3, the freezing point being-89.0 ℃, flash point being 36~38 ℃, self-ignition point being 689F and the refractive index being (n20D) 1.3993. At 20 ℃, its solubility in water is 7.7% (by weight) while the water solubility in 1-butanol was 20.1% (by weight).
Jun 26, 2024 · Wurtz measured the boiling point of ethylene oxide as 13.5 °C (56.3 °F), slightly higher than the present value, and discovered the ability of ethylene oxide to react with acids and salts of metals. Wurtz mistakenly assumed that ethylene oxide has the properties of an organic base.

Jun 24, 2024 · The boiling points of the rare-earth metals vary by nearly a factor of three. Those of lanthanum, cerium, praseodymium , yttrium, and lutetium are among the highest of all the chemical elements, while those of europium and ytterbium can be placed in the group of metals with the lowest boiling points.
