Which heat-transfer mode requires bulk motion of a fluid?

That mode is convection.

  1. Conduction
  2. Radiation
  3. Convection ✔

Why: Convection carries thermal energy as a liquid or gas moves. It may be natural, driven by buoyancy, or forced by a fan or pump.

Huh, didn't know that: In natural convection, heated fluid often rises after thermal expansion lowers its density.

The dad joke
Convection goes with the flow.
