evaporative cooling
Evaporative cooling is a natural process where a liquid turns into a gas, absorbing heat in the process. When water evaporates from surfaces, like skin or wet clothing, it takes away heat, cooling the surrounding area. This principle is why sweating cools us down; as sweat evaporates, it helps regulate body temperature. Evaporative coolers, or swamp coolers, utilize this process by blowing air over water-saturated pads, effectively lowering the air temperature and increasing humidity. This method is energy-efficient and works best in dry, hot climates, where the evaporation rate is higher.

Evaporative cooling is a natural process where water absorbs heat when it evaporates, transforming from liquid to vapor. This process cools the surrounding air, which is why you feel cooler when you sweat or splash water on your skin. In practical applications, evaporative coolers, often used in dry climates, draw warm air through water-saturated pads, cooling the air before it enters a space. It's an energy-efficient method of cooling, utilizing the basic principle of heat absorption during evaporation, making it a popular choice for many homes and businesses.
