25 de abr. de 2024 · gas, one of the three fundamental states of matter, with distinctly different properties from the liquid and solid states.. Structure. The remarkable feature of gases is that they appear to have no structure at all. They have neither a definite size nor shape, whereas ordinary solids have both a definite size and a definite shape, and liquids have a definite size, or volume, even though they ...
Hace 2 días · List. 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.
2 de may. de 2024 · Hugo Lin, ThoughtCo. Solids, liquids, and gases are the three primary states of matter. Understanding these states is crucial because they are fundamental concepts in chemistry and physics, and you might encounter phase changes in real life—from boiling water to freezing ice and condensation.

The mixture contains a group of gases of nearly constant concentrations and a group with concentrations that are variable in both space and time. The atmospheric gases of steady concentration (and their proportions in percentage by volume) are as follows: nitrogen (N 2) 78.084.
Hace 5 días · An atmosphere (from Ancient Greek ἀτμός (atmós) 'vapour, steam', and σφαῖρα (sphaîra) 'sphere') is a layer of gasses that envelop an astronomical object, held in place by the gravity of the object. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low.
