Conduction
Conduction is described as the transfer of heat among solids. Due to increased molecular vibration, heat from one molecule of higher temperature is transferred to the adjacent molecules that the molecule with higher temperature comes in contact with.
Metals are the best conductors of heat because they have many free electrons that vibrate and easily come in contact with other electrons, thereby making heat transfer much easier. Cloth, wood, and plastic are examples of insulators, or poor conductors of heat. Think of a metal spoon left in a pan of boiling water. After a while, even the part of the spoon that was not submerged in the boiling water has also become hot.
