Final answer:
Heat transfer through the movement of smoke, hot air, and heated gases is known as convection, which involves the macroscopic movement of a fluid.
Step-by-step explanation:
The method of heat transfer that occurs through the motion of smoke, hot air, and heated gases is convection. Convection is the transfer of heat by the macroscopic movement of a fluid, which can include gases and liquids. Unlike conduction, which involves heat transfer through stationary matter by physical contact, convection involves the movement of mass. An example of convection is the hot air rising above a heater or the circulation of heat in a pot of boiling water.
