- - - - transmitted through a solid object.
      - Jiggling particles pass their energy to their neighbours
      - Metals conduct heat better than non-metals
    - - One end of the rod is heated, the molecules gain energy and vibrate faster.
      - These molecules collide with their less energetic neighbors, transferring energy to their neighboring molecules which in turn gain kinetic energy.
      - This transfer of energy from molecule to molecule continues until the cold end reaches the same temperature as the hot end.
    - - The molecules in solids are closer together than in liquids and gases. Collisions between molecules in solids are more frequent such that kinetic energy can be transferred more quickly.
  - - - Conduction is when more energetic (hotter) particles move upwards in a gas or liquid
    - - occurs in gases and liquids (fluids) as the molecules are free to move about. heat rises due to convection. This makes convection currents
    - - When the liquid is heated, it expands, become less dense and rises up to the surface.
      - When it reaches the surface, the liquid is cooled; it contracts, become denser and sinks to the bottom.
      - The circulation of a liquid in the above manner is called convection current.
