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 (abbreviated RH) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at the same temperature.Relative humidity depends on temperature and the pressure of the system of interest.he relative humidity of an air-water mixture is defined as the ratio of the partial pressure of water vapor in the mixture to the equilibrium vapor pressure of water at a given temperature: Relative humidity is normally expressed as a percentage; a higher percentage means that the air-water mixture is more humid.
