If I have water or air in a closed container for several years, it is said to go "stale". What does this mean exactly? What kind of physical changes has it undergone?

Ok I understand, woul dit be possible to restart the circulation of the air molecules by vigorous shaking of the container or by heating it...?

It's kind of like powdered chocolate milk. You know how if you don't stir it enough, all the chocolate powder settles at the bottom? It's kind of like that with air or water. After a while, the water/air stops moving, and the parts separate. Thus, the water no longer has air in it, which makes it taste fresh, and the air is no longer moving, thus it smells stale. That was an excellent question.

I can't tell you the physical difference, if any, between "stale" air and air that isn't considered so. Generally speaking, stale air is air that has been enclosed in a house, a room, or some other enclosure where there has been little or no air movement or new air coming in. As far as "stale" water, there is not such thing, Water cannot spoil. It has an indefinite shelf life, meaning that water properly stored will be consumable forever. Stale water used to refer to stagnant water. In most cases it's wise to either avoid consuming stagnant water or to purify it in some manner. Boiling it for five minutes will kill the bacteria and make it drinkable. If the water is too dirty for immediate use, it can be allowed to sit and the particles will settle to the bottom of the container, then the water can be used if you don't disturb the sediment. There are other ways to purify water simply and easily, but that's more than you asked for.
I hope this helped.

It doesn't necessarily mean it's unhealthy, only that it has been uncirculated. Stale air has been in an enclosed space for a long time and may have an unpleasant dry or musty smell to it, and is more a product of the environment it's in rather than its chemical composition -- an old attic might have stale air, yet have enough cracks and holes that the oxygen levels are the same as outside. I don't recall having heard water referred to as "stale," but it might be the same as flat -- no dissolved oxygen in it, and if it's in a soft plastic bottle, it might have pthalates in it that have leeched out of the plastic during storage, giving it a distinctly plastic flavor. If you're thinking of stagnant water, that's a little different, because it typically refers to water in an outside setting, where it sits uncirculated for long periods of time (ponds, near the shore of slow-running rivers, puddles, or shaded low spots where water is kept from evaporating very quickly, like in an old tire in a junkyard or something). Stagnant water may be flat or stale, but it is unhealthy to drink because stagnant water promotes bacterial growth (well-oxygenated water from a fast-moving river doesn't have nearly the same level of bacterial contamination as stagnant water)

Just air that doesn't circulate. Shut all the doors all the windows in your room go to sleep and wake up and the whole room smells like your breath. That is stale. As for water that is the same thing. No movement or oxygen filtered through the water.

if anything sits for a long time it stagnates and starts tasting and smelling funny. it picks up contaminates and can't get rid of them so it's considered stale
