A gas giant is a giant planet composed mainly of hydrogen and helium. [1] Jupiter and Saturn are the gas giants of the Solar System. The term "gas giant" was originally synonymous with "giant planet". However, in the 1990s, it became known that Uranus and Neptune are really a distinct class of giant planets, being composed mainly of heavier ...
This glossary of chemistry terms is a list of terms and definitions relevant to chemistry, including chemical laws, diagrams and formulae, laboratory tools, glassware, and equipment. Chemistry is a physical science concerned with the composition, structure, and properties of matter , as well as the changes it undergoes during chemical reactions ...
Sudarsky's classification of gas giants for the purpose of predicting their appearance based on their temperature was outlined by David Sudarsky and colleagues in the paper Albedo and Reflection Spectra of Extrasolar Giant Planets [1] and expanded on in Theoretical Spectra and Atmospheres of Extrasolar Giant Planets, [2] published before any successful direct or indirect observation of an ...
This is the ratio found in the gas giant planets, such as Jupiter. The analysis of deuterium–protium ratios (2 H 1 HR) in comets found results very similar to the mean ratio in Earth's oceans (156 atoms of deuterium per 10 6 hydrogen atoms). This reinforces theories that much of Earth's ocean water is of cometary origin.
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).
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.

Saturn is a gas giant, composed predominantly of hydrogen and helium. It lacks a definite surface, though it is likely to have a solid core. [ 37 ] The planet's rotation makes it an oblate spheroid —a ball flattened at the poles and bulging at the equator.
