The movement of heated gases in a fire is an example of which form of heat transfer?

The movement of heated gases in a fire exemplifies convection because convection is the process by which heat is transferred through the motion of fluids, including gases. In a fire scenario, as gases are heated, they become less dense and rise, creating a flow of air that carries heat away from the fire's source. This cycle continues as new, cooler air is drawn in to replace the rising heated gases, facilitating the transfer of thermal energy throughout the environment.

This principle of convection is fundamental in understanding fire behavior and dynamics, as it significantly affects the spread of fire and smoke within a structure. It illustrates the importance of recognizing how heated air and gases behave, which is crucial for effective firefighting strategies and ensuring safety during fire incidents.
