Some topics that have been explored in the past are:

1) A comparison between the energy content of various liquid and gaseous fuels for automotive use, taking into consideration energy content per unit volume or unit weight.

2) The determination of the temperature dependence of the specific heat of materials.

3) A study of heat pipes for thermal energy transport.

4) Heat transfer between parallel glass plates to evaluate heat losses from a building through its windows.

5) The use of the differential thermal expansion between two metals to measure temperature or to make a temperature sensitive actuator (bi-metal strip).
