  • what is conduction
    • where heat is transferred by solids as vibrating particles transfer energy to neighbouring particles
    • causes particles to vibrate faster and collide with neighbouring particles more often allowing energy to transfer along the metal until evenly distriputed.Particles are held closely in a solid.Thermal conductive.
  • convection
    • flids (liquids and gases)
    • no fixed so once heated allow of them move faster causing energetic particles from heat to move away from warmer region to those in the colder region causes it to expand
    • repetition is a convection current
  • differences
    convection - particles move
    conduction - energy is tranasferreds
  • radiation
    • transferring energy without particles
    • infrared radiation - hotter an object more energy is transferred via radiation
