1. Relative Humidity Concept

Relative humidity (RH) is a measure of the amount of water vapor in the air compared to the maximum amount of water vapor the air can hold at a given temperature. It is expressed as a percentage, ranging from 0% (completely dry) to 100% (completely saturated with water vapor).

Factors Influencing Relative Humidity

• Temperature:Warmer air can hold more water vapor than cooler air.
• Amount of water vapor:The more water vapor in the air, the higher the relative humidity.
• Pressure:Higher pressure reduces the amount of water vapor the air can hold, resulting in lower relative humidity.

Relationship between Temperature and Relative Humidity

As temperature increases, the maximum amount of water vapor the air can hold increases. Therefore, the same amount of water vapor will result in a lower relative humidity at higher temperatures.

Essential FAQs

What is the definition of relative humidity?

Relative humidity is the ratio of the actual amount of water vapor in the air to the maximum amount of water vapor the air can hold at a given temperature.

How does temperature affect relative humidity?

As temperature increases, the air’s capacity to hold water vapor increases, resulting in a decrease in relative humidity. Conversely, as temperature decreases, the air’s capacity to hold water vapor decreases, leading to an increase in relative humidity.

What are the applications of relative humidity in industries?

Relative humidity plays a crucial role in industries such as manufacturing, agriculture, and healthcare, where it influences product quality, crop yields, and human comfort.
