The maximum amount of water contained in air at various temperatures and pressure is indicated on a psychrometric chart. The carrying capacity changes with these parameters. The actual humididty can be read out from wet and dry bulb thermometer temperature measurement. However at 100% carrying capacity y the relative untidy is always 100 percent.
When a parcel of air is saturated with water vapor the relative humidity of that parcel of air is 100%.
100%
That would be "dewpoint"...When the air temperature falls to the dewpoint (or dewpoint rises to the air temperature), then you have 100% relative humidity.
warm
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.
When the air is saturated, the relative humidity is 100%. This means that the air is holding the maximum amount of water vapor it can at that particular temperature and pressure.

When air is saturated at 30 degrees celsius
Saturated
100% if it is completely saturated.
The comparison of the actual amount of water vapor in the air to the amount of water vapor in the air if it were saturated is called relative humidity. It is expressed as a percentage and indicates how close the air is to being saturated with moisture.
This is called relative humidity. It is the ratio between the actual humidity, and the humidity for saturated air - that is, the maximum amount of water air can hold. This saturation point is dependent on temperature.
