Final answer:
Radiation is the method of heat transfer that most strongly influences the rate of burning in a growing fire.
Step-by-step explanation:
The method of heat transfer that most strongly influences the rate of burning in a growing fire is radiation.
When a fire burns, it emits thermal energy in the form of infrared radiation. This radiation can travel through space and air, and it is responsible for transferring heat to the surrounding objects and air, facilitating the spread of the fire. As a result, radiation plays a crucial role in sustaining and accelerating a fire.
In contrast, conduction refers to the transfer of heat through direct contact between objects and is slower in comparison. Convection involves the movement of hot air, which can contribute to the spread of a fire, but is not as influential as radiation.
