Factors Affecting Evaporation
Evaporation is defined as the process by which a liquid changes into a vapor or gaseous state. It is affected by various factors which are explained below:
- Humidity: It is defined as the amount of water vapor present in the atmosphere which is usually high during the rainy season. When there is high humidity, the rate of evaporation slows down because vapors are already present in the air.
- Temperature: There is a direct relationship between temperature and the rate of evaporation. In the case of higher temperatures, the rate of evaporation increases, while at lower temperatures the rate of evaporation decreases.
- Surface Area: We spread clothes over a large area to dry them, why? The greater the surface area, the higher the rate of evaporation. During this process, surface particles are converted into vapor, so if there is a large surface area, the rate of evaporation will increase, and vice versa.
- Wind Speed: The rate of evaporation is directly proportional to the wind speed. This means that evaporation accelerates when the wind speed is high, and vice versa.
