Question

what form of heat transfer is shown in the image below? *
options: conduction, convection, radiation

Explanation:

Heat transfer by conduction occurs through direct contact of particles. In the image, heat moves along the rod (a solid) from the hot end (near the flame) to the cooler end. Convection involves fluids (liquids/gases) and bulk movement. Radiation is heat transfer via electromagnetic waves (like the Sun's heat reaching Earth). Here, the rod's material (solid) and direct particle - to - particle heat movement fit conduction.

Answer:

Conduction
