Which type of heat transfer occurs via air movement?

Convection is the type of heat transfer that occurs via air movement. This process involves the movement of fluids, which can include liquids and gases, where warmer areas of a liquid or gas rise and cooler areas sink. This creates a circulation pattern that facilitates the transfer of heat. In the context of air movement, when air is heated, it becomes less dense and rises, while cooler air moves in to take its place. This circulation effectively distributes heat throughout a space, making convection a fundamental concept in both heating and cooling systems as well as in natural phenomena such as wind patterns. Understanding convection is crucial in interior design, particularly when considering HVAC systems and thermal comfort within spaces.
