Conduction: THE PROCESS WHERE VIBRATING PARTICLES PASS ON EXTRA KINETIC ENERGY TO NEIGHBOURING PARTICLES.

1) Heat flows from the warm inside face of a window to the cold outside face by conduction.
2) In a solid, particles are held tightly together, so when ONE particle vibrates, it bumps into the others and makes them vibrate.
3) Particles which vibrate faster then pass on their kinetic energy to the other particles, causing these particles to move even faster.
4) This process continues throughout the solid until the extra kinetic energy (or heat) has spread through all of the solid - this causes the raise in temperature on the other side.
5) Metals conduct heat well because some of their electrons are free to move. Heating makes electrons move faster and collide with other free electrons, transferring energy. These then pass on their energy to other electrons.
6) Because the electrons move freely, it is a…
