The term for the process of heat transfer through indirect contact is called convection. This process occurs in fluids (liquids and gases) where warmer, less dense areas rise while cooler, denser areas sink, creating circulation. Convection is significant in various natural phenomena, including weather patterns and ocean currents. It is also applied in engineering, particularly in heating and cooling systems. Understanding convection is essential for predicting thermal behavior in physical systems where heat transfer plays a critical role.
