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...

Saturation
Not saturated - it could hold more Saturated Beyond saturation - it can't hold this much
