The correct option that represents a model of thermal energy transfer by conduction is option A: Freezing ice cubes in a freezer.
Model of Thermal Energy Transfer by Conduction:
Conduction is a process of heat transfer through direct contact between particles. In the case of freezing ice cubes, the transfer of thermal energy occurs through the direct contact of the warmer water molecules with the colder surroundings, typically the walls of the ice cube tray and the air in the freezer. As the heat moves from the warmer water to the colder surfaces, the water loses energy, leading to the formation of ice.
Contrastingly, options B, C, and D involve different modes of heat transfer. Option B involves radiation as the heat from the lamp is emitted in the form of electromagnetic waves. Option C involves convection, where heat is transferred through the movement of fluids like air or water. Option D involves forced convection as the fan accelerates the movement of air, aiding in cooling through increased air circulation.
Therefore, the model representing thermal energy transfer by conduction is freezing ice cubes in a freezer (Option A).
