Transfer of Thermal Energy, The relationship between thermal energy and…

- - - - Lower thermal energy
      - Slow particle movement
    - - Higher thermal energy
      - Fast particle movement
  - - - Not a form of energy
      - Measures kinetic energy of particles
      - Measurement of hotness
      - Related to particle kinetic energy
    - - Thermal energy transfers to air
    - - Can be transferred
- - - - As the heat is supplied, particles move faster. These particles bump into neighbours and in turn transfer kinetic energy. This process continues across the object.
    - - Thermal Conductors allow conduction easily as the particles are close together. This allows easy energy transfer through good conductors such as Metals.
    - - Conduction is the transfer of thermal energy through a solid object. These particles do not move location and directly contact with each other.
    - - Thermal Insulators resist conduction as the particles are further apart. This prevents conduction from easily traveling through an object e.g. plastics and Polystyrene.
    - - Close particles = Better conduction of heat energy. Efficient energy transfer through bumping of particles.
      - Particles far apart = less efficient conduction of heat energy. This is because of more of a spread between particles, causing less bumping and therefore less transfer.
