Question

____ occurs when thermal energy is transferred as the particles of sub

convection

conduction

resistance

radiation

Explanation:

• Convection: Thermal energy transfer through particle movement (e.g., in fluids).
• Conduction: Thermal energy transfer through direct particle - to - particle contact (e.g., in solids).
• Resistance: Opposes electric current, not thermal energy transfer as described.
• Radiation: Thermal energy transfer via electromagnetic waves (no particle movement in the sense of convection).

Since the question mentions thermal energy transfer as particles of a substance move (which is the key characteristic of convection), we analyze each option.

Answer:

Convection
