The Joule’s Calorimeter is a fully assembled unit designed for determining the specific heat capacity of a liquid using the electrical method.
It includes an insulated top plate, two 4mm diameter socket head terminals, a compact heating element, and a plastic stirrer. These components work together to ensure accurate and efficient experimentation.
Heating Element & Electrical Specifications
The heating coil provides an approximate resistance of 2 ohms, making it suitable for operation within a voltage range of 2 to 12 V.DC. This precise control over the heating process allows for accurate experiments involving liquid substances.
The unit is specifically designed to be used with a standard copper calorimeter cup measuring 50mm in diameter and 75mm in depth, ensuring compatibility with conventional laboratory setups.
Experimental Applications
The primary function of the Joule’s Calorimeter is to elevate the temperature of liquids, typically water, to determine the electrical equivalent of heat. By measuring the energy required to raise the temperature of a known quantity of water by a specific amount, users can perform accurate thermal energy calculations, making it a valuable tool for physics and chemistry experiments.
How to Avoid Corrosion
Thoroughly dry the vessel after cleaning to prevent moisture-induced copper corrosion.
Store the vessel in a cool, dry area with low humidity.
For extra protection, wrap the vessel in a sealed plastic bag with silica gel packets to absorb residual moisture.
DISCLAIMER! Breaches in the nickel plating may still pose a challenge in fully preventing corrosion.

What is the best way to clean the calorimeters without causing them to corrode?
Question by: Jess on 18 Feb 2025, 9:43 pm
Below are the few points to keep in mind while using these calorimeters:
· To help prevent copper corrosion, it's best to ensure that the vessel is thoroughly dried after cleaning. Even a small amount of remaining moisture can speed up the corrosion process. We recommend storing the vessel in a cool, dry area with low humidity.
· For extra protection, you might consider wrapping the vessel in a sealed plastic bag with some silica gel packets to absorb any residual moisture.
· Please note, if there are any breaches in the nickel plating, it may be challenging to fully prevent corrosion.
