Key Stage 3
Meaning
Conduction is when thermal energy passes along a material from the hotter region to the cooler region.
 |
| Grey represents the metal bar at a cold temperature. The yellow represents the highest temperature and red represents a temperature between yellow and grey. |
About Thermal Conduction
- Of the three states of matter, solids are the best conductors of thermal energy.
- Metals are better thermal conductors than non-metals because metals have free electrons that can pass along thermal energy.
