Conduction

Conduction

1. Thermal conduction

   • Thermal conduction is the transfer of heat by microscopic collisions of particles and movement of electrons within a body.

2. Heat conduction

   • Heat conduction (or thermal conduction) is the movement of heat from one solid to another one that has different temperature when they are touching each other

3. Example

   • After a car is turned on, the engine becomes hot. The hood will become warm as heat is conducted from the engine to the hood.

4. Conduction transfers heat within a body or between two bodies that are touching

5. Electrical conduction

   • In electrical conduction, energy is transferred by the movement of electrons or ions

6. non-metals and gases are usually poor conductors of heat

7. Metals are good conductors of heat

8. Why are most metals good conductor of heat and electricty

   • The free electrons in metals can move through the metal, allowing metals to conduct electricity.
