Thermal Conductivity Heat can be transferred in three different ways: convection‚ radiation and conduction. Conduction is the way heat is transferred in a solid‚ and therefore is the way it is transferred in a heat sink.

At the point where the two objects meet‚ the faster moving molecules of the warmer object crash into the slower moving molecules of the cooler object. When this happens‚ the faster

Thermal expansion is the tendency of matter to change in volume in response to a change intemperature.[1] All materials have this tendency. When a substance is heated‚ its particles begin moving more and thus usually maintain a greater average separation. Materials which contract with increasing temperature are rare; this effect is limited in size‚ and only occurs within limited temperature ranges. The degree of expansion divided by the change in temperature is called the material’s coefficient
