Conduction

• Conduction


  The process where vibrating particles transfer energy to neighbouring particles
• Conduction


  • Occurs mainly in solids
  • Particles in liquids and gases are much more free to move around which is why they usually transfer energy by convection instead of conduction
• Conduction


  1. Energy transferred to an object by heating is transferred to the thermal store of the object

  2. The particles in the part of the object being heated vibrate more and collide with each other, causing energy to be transferred between particles' kinetic energy stores

  3. This process continues throughout the object until the energy is transferred to the other side of the object

  4. The energy is then usually transferred to the thermal energy store of the surroundings (or anything else touching the object)
• Thermal conductivity


  • A measure of how quickly energy is transferred through a material
  • Materials with a high thermal conductivity transfer energy between their particles quickly
• Energy is transferred by conduction through the metal pan handle


  Energy is transferred by conduction through the pan to the water
