Conduction

Conduction

1. Conduction of heat energy is the process where vibrating particles pass on their extra kinetic energy to neighbouring particles.

2. Conduction is faster in denser solids because the particles are closer together and so will collide more often and pass energy between them.

   • Materials that have larger spaces between their particles conduct heat energy much more slowly - these materials are INSULATORS.

3. The heat is passed all the way through the solid causing a rise in temperature and an increase in the heat radiating from its surface

4. Metals are good conductors because of their free electrons

5. Conduction is more efficient through a short, fat rod than through a long, thin rod because the electrons have less of a distance to move.
