Which term describes energy transfer by the movement of heated particles within a fluid?

Explanation:
Convection describes energy transfer by the movement of heated particles within a fluid. When part of a fluid is heated, those particles gain energy, become less dense, and rise, while cooler, denser fluid moves in to take its place, creating a circular flow that carries heat through the liquid or gas. This is why warm air rises and currents form in boiling water. Conduction, by contrast, is energy transfer through direct contact and particle interactions without bulk motion, and radiation is energy transfer by waves through space. Insulation slows heat transfer rather than moving it.
