conduction, convection or radiation?

Brief Explanations:

1. Toaster: Conduction as heat is transferred directly from heating - elements to bread.
2. Hair - dryer: Convection as it blows hot air (movement of heated fluid).
3. Iron: Conduction as heat is transferred from iron's hot surface to clothes.
4. Campfire: Radiation as heat is emitted in the form of electromagnetic waves.
5. Oven: Convection (hot air circulation) and Radiation (emission of heat waves).
6. Person sunbathing: Radiation as heat from the sun reaches the person via electromagnetic waves.
7. Grill: Conduction (direct heat transfer from grill surface to food) and Radiation (heat emitted from fire).
8. Microwave: Radiation as it uses microwave radiation to heat food.
9. Cup of coffee cooling: Conduction (heat transfer to cup and then to air), Convection (air movement around cup) and Radiation (emission of heat waves).
