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 ...
Lutetium is a chemical element; it has symbol Lu and atomic number 71. It is a silvery white metal , which resists corrosion in dry air, but not in moist air. Lutetium is the last element in the lanthanide series, and it is traditionally counted among the rare earth elements ; it can also be classified as the first element of the 6th-period ...
Gas: A compressible fluid. Not only will a gas take the shape of its container but it will also expand to fill the container. Mesomorphic states: States of matter intermediate between solid and liquid. Plastic crystal: A molecular solid with long-range positional order but with constituent molecules retaining rotational freedom.
Drifting smoke particles indicate the movement of the surrounding gas.. Gas is one of the four fundamental states of matter.The others are solid, liquid, and plasma. [1] A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide).
Sulfur (also spelled sulphur in British English) is a chemical element; it has symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with the chemical formula S 8. Elemental sulfur is a bright yellow, crystalline solid at room temperature.
For a given mass of gas at constant temperature, the volume varies inversely with the pressure. Bragg's law bridge A chemical bond between valence electrons, or an atom or unbranched chain of atoms connecting two different parts of the same molecule; i.e. an intramolecular bond linking different moieties or functional groups.

Under normal conditions germanium tetraiodide (GeI 4) is a solid, germanium tetrafluoride (GeF 4) a gas and the others volatile liquids. For example, germanium tetrachloride , GeCl 4 , is obtained as a colorless fuming liquid boiling at 83.1 °C by heating the metal with chlorine. [ 36 ]
"Living Made Easy": A satirical print from 1830 depicting Humphry Davy administering a dose of laughing gas to a woman. The first important use of nitrous oxide was made possible by Thomas Beddoes and James Watt, who worked together to publish the book Considerations on the Medical Use and on the Production of Factitious Airs (1794). This book ...
