📊 Comparing the Three Methods
SUMMARY: CONDUCTION vs CONVECTION vs RADIATION
| Property | CONDUCTION | CONVECTION | RADIATION |
|---|---|---|---|
| Works in | Mainly SOLIDS (best in metals) | LIQUIDS & GASES (fluids only) | ALL states + VACUUM |
| How it works | Vibrations pass particle to particle (+free electrons in metals) | Hot fluid rises, cold fluid sinks (density change) | Infrared EM waves travel (no particles needed) |
| Particles move? | NO (vibrate in position) | YES (whole fluid moves) | NO particles involved |
| Example | Metal spoon in hot drink | Hot air balloon rising | Sun warming the Earth |
