Practice question · Match the pairs
Match each heat transfer mechanism to its description.
- Conduction
- Convection
- Radiation
- Advection
- Heat flow through a material by molecular collisions
- Heat transport by directed bulk fluid flow (a type of convection)
- Heat carried by bulk fluid motion
- Heat transferred via electromagnetic waves
Hints
- Ask what each mechanism needs: contact, a moving fluid, or nothing.
- Only one of them works across empty space.
Show the answer
- Conduction → Heat flow through a material by molecular collisions
- Convection → Heat carried by bulk fluid motion
- Radiation → Heat transferred via electromagnetic waves
- Advection → Heat transport by directed bulk fluid flow (a type of convection)
Why
Conduction requires direct contact, convection needs a fluid medium, radiation needs neither.
