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).
A vapor can exist in equilibrium with a liquid (or solid), in which case the gas pressure equals the vapor pressure of the liquid (or solid). A supercritical fluid (SCF) is a gas whose temperature and pressure are above the critical temperature and critical pressure respectively. In this state, the distinction between liquid and gas disappears.
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 ...

Inhaling nitrous oxide from Galaxy Gas products is the latest trend among kids who misuse laughing gas for a quick high. Here’s what parents should know. Kids are inhaling ‘Galaxy Gas’ to ...
The helium molar fraction, i.e. the number of helium atoms per molecule of gas, is 0.15 ± 0.03 [22] in the upper troposphere, which corresponds to a mass fraction 0.26 ± 0.05. [ 18 ] [ 95 ] This value is close to the protosolar helium mass fraction of 0.275 ± 0.01 , [ 100 ] indicating that helium has not settled in its centre as it has in ...
In the gas phase, it can image cavities in a porous sample, alveoli in lungs, or the flow of gases within the lungs. [177] [178] Because xenon is soluble both in water and in hydrophobic solvents, it can image various soft living tissues. [179] [180] [181] Xenon-129 is currently being used as a visualization agent in MRI scans.
Given how much we cherish Costco, you'd think we'd know everything about the mega-retailer, but Costco is, in many ways, a complicated beast with a lot of interesting trivia bubbling beneath the ...
