Albertgauss said:Does anyone know of a reference to a list of all known chemicals that freeze at less than 50 K? I know lots of organic molecules do, but I don't know which ones. I also can find the freezing points of all the elements pretty easy, but chemicals are proving more elusive.
A chemical that freezes at less than 60 Kelvin is a substance that solidifies at a temperature below 60 Kelvin (or -213.15 degrees Celsius). This means that the molecules in the substance lose enough energy to slow down and form a solid structure.
Some examples of chemicals that freeze at less than 60 Kelvin include neon, helium, and hydrogen. These elements have very low boiling points and can freeze at extremely low temperatures.
The freezing point of a chemical is determined by its molecular structure and intermolecular forces. Substances with weaker intermolecular forces, such as noble gases, will have lower freezing points compared to substances with stronger intermolecular forces.
Chemicals that freeze at less than 60 Kelvin have various potential uses, such as in cryogenic applications, superconductors, and cooling agents. They are also used in scientific research and experiments, as well as in the production of certain materials.
Yes, there are safety concerns when handling chemicals that freeze at less than 60 Kelvin. These substances are extremely cold and can cause serious burns if they come into contact with skin. Protective gear and proper handling techniques should be used when working with these chemicals.
