Question

Humidity is the quantity of ___________ present in the air?

Answer 1

Hint:Humidity is an important characteristic that is responsible for the change in factors of climate and weather in the atmosphere. We are going to discuss the factors that are responsible for humidity. Humidity plays an essential role in surface life on the earth because animals and human beings naturally can regulate the internal body temperature by sweating.

Complete step-by-step solution:
Climate is the long-term patterns of wind, humidity, temperature, precipitation, etc. in an area. When compared to Climate, the weather is the short-term conditions of the atmosphere. But Climate is the condition which exists for a particular location for $30$ years.
For example, It becomes hot when our body reacts to sunlight by sweating and that means water on our skin during sweating takes latent heat away from our body to help to cool down.
Humidity means the amount of water vapor present in the air varies with the temperature change. Humidity can be calculated by the ratio of actual vapor pressure in air to the vapor pressure at saturation.
From the above discussions, we came to know that humidity is the amount of water vapor present in the air.

Note:Absolute humidity means the amount of water content of the air and it is represented by $\dfrac{g}{{{m^3}}}$. Relative humidity means the relation between absolute humidity to maximum humidity that can be expressed in percentage. Relative humidity means the ratio of the mass of water vapor to per unit mass of air. A psychrometer is used to measure the humidity. By using a Psychrometric chart, the humidity of the air and water vapor mixture was calculated by the known values of dry bulb temperature and wet bulb temperature.
