Explanation:
The ratio of the amount of water vapor in the air to what is needed to reach saturation at a specific temperature and pressure is known as relative humidity. When the relative humidity is 100%, an air parcel is fully saturated.
<h3>What is relative humidity?</h3>
Water vapor is measured by relative humidity as well, but relative to air temperature.
In other words, it is a comparison between the amount of water vapor that is actually present in the air and the maximum amount of vapor that is possible for the air at the current temperature.
The proportion of water vapor in the air at a specific temperature is known as relative humidity. The amount of humidity is used to forecast whether it will rain, fog, or mist.
Climate control relies on relative humidity, which has an impact on people's health, comfort, and safety.
When compared to the maximum quantity of water vapor that could be present in the air at a given temperature, relative humidity is expressed as a percentage.
