Heat Conduction

Heat transfers because of temperature gradient, resulting in mutual exchange of heat energy within single object or among several. When the temperatures in two objects are not the same, heat energy always transfers from the one of high temperature to that of low temperature. The philosophy behind it is the transfer of kinetic energy because forces act among the atoms and molecules. The purpose of this experiment is to study the transfer of heat and determine the rate of heat conduction. Also, practice the principle of thermal couples in the experiment.





Plug thermocouple to the multimeter and read the voltage readings to determine the temperature of the heat capacitor.

Copper Heat Capacitor
There are thermocouple and asbestos plate inside the copper heat capacitor.
When thermocouple is subjected to a thermal gradient, it will generate a voltage. The asbestos plate surrounds the heat capacitor used to inhibit heat transfer.

To measure the thermal conductivity of the glass samples.
Copper Cylinder
With good heat dissipation and lower the temperature of the heat capacitor.

Copper Pot
Put the copper pot on a heat source for the water to boil.
The thickness of its bottom is 0.4 cm. Thermal conductivity k is 109 J / s‧m‧℃.
