Key Features
Capacity 350 ml
Heating coil with electrical terminals for a low-voltage supply
Insulated outer container, lid, stirrer and thermometer opening
Heat energy is calculated from voltage, current and heating time
Used for Joule’s law of heating and specific heat capacity experiments
With water in the vessel and the coil connected, students switch on, start a timer and stir while recording voltage, current and the temperature rise. Comparing the heat taken up by the water with the electrical energy supplied makes Joule’s heating effect and energy conversion concrete.
Frequently Asked Questions
What readings are taken with the Electric Calorimeter 350 ml?
The initial and final water temperature, the voltage, the current and the heating time. These give the heat gained by the water and the electrical energy supplied, for comparison.
