What is Evaporation?

Evaporation is the process by which a liquid, such as water, changes into a vapor or gas due to an increase in temperature and/or pressure.

Factors Affecting Evaporation

• Temperature: Higher temperatures lead to increased evaporation as the molecules in the liquid gain more energy to escape into the air.
• Surface Area: A larger surface area results in more evaporation, as more liquid molecules are exposed to the air.
• Humidity: Lower humidity levels promote faster evaporation, as the air can hold more water vapor.
• Wind: Wind can carry away the water vapor from the liquid's surface, allowing for more evaporation to occur.

Applications of Evaporation

Evaporation is widely used in industries for processes such as drying of clothes, food preservation, and production of salt from seawater.

Water Cycle

In the water cycle, evaporation is the first step where water from bodies of water, such as oceans, lakes, and rivers, is heated by the sun and evaporates into the atmosphere as water vapor.

Conclusion

Evaporation is a fundamental process in the natural world and plays a crucial role in the water cycle and various industrial applications.
