How does convection differ from conduction in terms of heat transfer?
How does convection differ from conduction in terms of heat transfer?
- Convection moves through fluids, while conduction transfers heat through contact (correct)
- Convection occurs through direct contact, while conduction uses fluid movements
- Convection uses electromagnetic waves, while conduction involves movement of fluids
- Convection happens at a distance, while conduction requires a medium to move through
