Answer Details
A relative humidity of 100 percent means that air is saturated. Relative humidity is the ratio of the amount of moisture in the air to the maximum amount of moisture that can be held at a given temperature. When the air is holding the maximum amount of moisture that it can hold, it is considered to be saturated. Therefore, a relative humidity of 100 percent indicates that the air is fully saturated with moisture, and any further addition of moisture would result in condensation, such as dew or fog.
