Some students see the more obvious ‘heat’ of very hot objects as different from that of objects at lower temperatures

For example, the Sun or a flame compared with the human body or a cup of tea.

  This resource explores the difference between temperature and thermal energy --

  • Temperature is termed an intensive quality since it does not depend upon the number of particles (or mass of substance) present.
  • Thermal energy is an extensive quantity since it depends upon the number of particles (or mass of substance) present.

• Helpful language for energy talk (11-16)

  Ref - Practical Physics; Energy; Introducing energy; Helpful language for energy talk

  There are a limited number of energy stores - thermal (in a warm object) being one.

  One energy carrier or pathway, is by heating (because of a temperature difference).

  An object thought of as a 'hot' object  simply has a larger store of thermal energy and can  transfer more by the action of heating.
