Moving and storing heat

Physics revision

Heating is all about the transfer of energy.

Heat is a measure of energy:

  • When a substance is heated its particles gain energy. This then makes the particles in a gas or liquid move around faster. However, in a solid the particles vibrate more rapidly.
  • Energy is measured on an absolute scale. This means it can't go lower than 0 because there is a limit on how slow particles can move.
  • Heat is measured in joule (J).

Temperature is the measure of hotness:

  • The hotter the object the higher the temperature.
  • Temperature is measured in degrees celsius. However, there is another scale…
