The usual cause is when air is holding the maximum amount of water possible.
Typically, yes. As air rises it cools, which can cause moisture in it to condense.
Saturated air is air that has all the water vapor that it can hold.
This will cause condensation. You could get a cloud or dew.
To determine if the air in the room is saturated or unsaturated, you would need to measure the humidity level. If the humidity level is at 100%, then the air is saturated. If it is below 100%, then the air is unsaturated.
There is not enough information to determine this. Just being at sea level does not cause the air to have a specific saturation (humidity).
Exhaled air is saturated with water vapor because the air we breathe in gets warmed and humidified in our lungs. As we exhale, this moisture-laden air is released, resulting in saturated air.
When a parcel of air is saturated with water vapor the relative humidity of that parcel of air is 100%.
Saturated air is more dense.
100%
more air
Yes, it is possible to determine if the air is saturated by looking at a Stuve graph. If the temperature and dew point lines are touching on the graph, then the air is saturated. If the lines are not touching, the air is not saturated.
"Saturated" or "At saturation point".
