In the fire environment, convection usually involves the transfer of heat through:

In the fire environment, convection is primarily concerned with the transfer of heat through the movement of fluids, which includes gases and liquids. In the context of a fire, this means that hot smoke and fire gases rise due to their lower density compared to the cooler air surrounding them. This upward movement is a key characteristic of convection and is often observed in fires, where the heat from the fire generates buoyant currents that carry smoke and hot gases upwards and can spread heat throughout a space.

By contrast, radiant heat typically refers to the transfer of energy through electromagnetic waves, mainly experienced as heat radiating from flames without direct contact. Direct contact with hot surfaces pertains to conduction, where heat is transferred through materials that are in contact with each other. Liquid water application is a method used in firefighting to extinguish fires, but it is not related to the convection process itself. Understanding these distinctions helps in recognizing how heat moves in a fire environment and how firefighters can effectively manage and control fire dynamics.
