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.
Resources to Address This
Temperature and particles related to energy (11-14)
Ref - SPT En05 PN02
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.View Resource
