Convection of air is the process by which warm air rises and cool air sinks, creating a circular motion in the atmosphere. This movement of air helps to distribute heat throughout a space, making it more comfortable for occupants. Convection currents can also transport moisture, pollutants, and other particles within the air, affecting air quality. In natural convection, these currents are driven by temperature differences, while in forced convection, external forces such as fans or pumps are used to move the air.
