The transfer of heat through the actual motion of heated particles is called convection.

Here's why:

* Conduction: Heat transfer through direct contact between particles, where energy is passed from one particle to the next.

* Convection: Heat transfer through the movement of fluids (liquids or gases). Warmer, less dense fluid rises, while cooler, denser fluid sinks, creating a cycle of movement that carries heat.

* Radiation: Heat transfer through electromagnetic waves, which can travel through space.
