Humidity is the amount of water vapor in the air. Too much or too little humidity can be dangerous. For example, high humidity combined with hot temperatures is a combination that can be a health risk, especially for the very young and the very old. Humidity plays an important role in our daily weather.
Relative humidity refers to the air-water mixture and is expressed as the ratio of the partial pressure of the water vapor in the mixture to the equilibrium vapor pressure of water at a specific temperature over a flat surface of pure water.
