Gas is a state of matter characterized by its molecules or atoms being arranged without structure so that they are collectively fluid and have neither a definite shape nor a definite volume. A basic gas definition in chemistry or physics is that gas is one of the three fundamental states of ...
Vapour and gas have different properties, depending on how close the molecules are to each other. For example, when water turns into steam (vapour), it becomes hotter because the molecules are closer together and can transfer energy more easily. Gas doesn’t necessarily have to be hot, ...
Matter exists in three main states, solid, liquid, and gas. Solids have a definite shape and volume (for example Ice). Liquids, likewater, have a defined volume but can change their shape depending upon the container. Everyone needs one or more of the three states of matter in some way...

In 1802, Joseph Louis Gay-Lussac published results of similar, though more extensive experiments, indicating a linear relationship between volume and temperature. Gay-Lussac credited Charle's earlier work by naming the law in his honor. In the absence of this linkage, Dalton could have been in ...
