comparing conductivities

• The conductivity of materials can be compared by

  examining the time taken to transmit energy through them
•  A fan of rods made of different materials can be heated at one end with the same


  flame.

  
• Whichever rod gets hottest first at the other end is the

  best conductor.

  
• The material that heats the quickest is said to have a

  high thermal conductivity.

  
• Thermal conductivity is a measure of how well a material conducts energy when it is

  heated.

  A) different types of material

  B) tripod stand

  C) bench mat

  D) Bunsen burner

  
•  A house built of conducting materials like copper would be very cold to

  live in as energy would be able to leave the house easily.
