Calorimeter Joules

A Joule’s Calorimeter is a scientific apparatus designed to study the mechanical equivalent of heat by measuring the relationship between electrical energy supplied and the heat produced. It is widely used in physics laboratories to demonstrate Joule’s Law of Heating, which states that the heat produced in a conductor is directly proportional to the square of the current, the resistance, and the time of flow.

Product Description:-

Consisting of a nickel plated copper vessel with outer vessel of teak wood fitted with bakelite top with hole for thermometer, terminals connected to a coil of wire complete with stirrer & outer teakwood vessel for determining the specific heat capacity of liquid by electrical method.The calorimeter joules provides a reliable method for quantifying heat transfer in various physical processes. By accurately measuring temperature changes and applying calorimetric principles, students can explore the fundamental concepts of heat capacity, latent heat, and thermal equilibrium.

The calorimeter joules, a staple in physics labs, is a versatile instrument used to measure heat transfer during various physical processes. By immersing substances in a calorimeter and monitoring temperature changes, students can quantify the heat exchanged and explore concepts such as specific heat capacity and latent heat. This experiment offers a hands-on approach to understanding thermodynamics and heat transfer phenomena.
