  • Conductor: Conductors are those materials that allow heat to flow. 
    • Heat is thermal energy and it transferred from one place to another by conduction.
    • Metals are good conductors of heat.
  • Insulators or bad conductors: Insulators are those which do not allow heat to pass through them.
  • Some examples of Insulators:
    • wood
    • glass
