Humidity and saturation
When a gas (or a space) holds the maximum water vapour possible at a given temperature, it is said to be saturated. If extra water is added to a saturated has, or if its temperature is reduced, some of the water will condense.
Thinking about saturation is like thinking of a wet sponge...
|Not saturated - it could hold more||Saturated||Beyond saturation - it can't hold this much|
