===About Thermal Conduction===
: Of the three [[State of Matter|states of matter]], [[solid]]s are the best '''conductors''' of [[Thermal Energy Store|thermal energy]]. [[Solid]]s are better [[Thermal Conductor|thermal conductors]] because the [[particle]]s are touching one another allowing them to pass on their [[energy]] quickly.
: [[Metal]]s are better '''[[Thermal Conductor|thermal conductors]]''' than [[Non-metal|non-metals]] because [[metal]]s have [[Delocalised Electrons|free electrons]] that can pass along [[Thermal Energy|thermal energy]].
