Cooling is the process of reducing the temperature of an object or environment. This can be achieved through various methods, such as removing heat or using refrigeration systems. Common examples include air conditioning units and refrigerators, which help maintain comfortable temperatures in homes and preserve food. In nature, cooling occurs through processes like evaporation and radiation. For instance, when water evaporates, it absorbs heat from its surroundings, leading to a drop in temperature. This principle is also utilized in cooling towers and heat exchangers to manage temperatures in industrial settings and power plants.
