Energy and Thermal Physics

Misconception RESEARCH REVIEW

Many students are unable to explain maintained thermal equilibrium (an object being kept at a fixed temperature higher than its surroundings) in terms of a balance between heat (or energy) input and loss – but use instead of simple cause-effect reasoning focusing on the strength of the heater.

Diagnostic Resources

The following worksheets may help to identify whether students hold this particular misconception.

Resources to Address This

  • Hot houses (11-14)

    Ref - SPT En05 TA05

    This activity looks at the energy losses in a model house and provides an environment where several explorations are possible. Sensible actions rely on reasoning based in convection, conduction and radiation in trying to achieve a chosen goal for the house. 

    It is also possible to introduce the idea of thermal equilibrium.
