The specific heat of a certain object can be measured using calorimetry, which involves using a thermally insulated water container. This container consists of several components:
1. Thin container made of good heat conducting metal: The inner container, where the object whose specific heat is being measured is placed, is made of a thin container typically composed of a metal like copper. Copper is a good conductor of heat, allowing efficient heat transfer between the object and the water.
2. Outer container made of the same metal: The inner container is surrounded by another container made from the same metal, creating a double-walled setup. This outer container helps to provide additional insulation and minimize heat exchange with the surroundings.
3. Heat insulating material: Between the inner and outer containers, a heat insulating material such as sawdust or fibers is placed. This material acts as a thermal insulator, preventing heat transfer between the inner container and the outer container, as well as the surroundings.
. Cover with apertures: The container is equipped with a cover that has two apertures. The first aperture is for inserting a thermometer, which allows the measurement of the temperature of the water and the object inside. The second aperture is for inserting a stirrer to mix the water and ensure uniform temperature distribution.
By placing the object with a known mass into the calorimeter and measuring the initial and final temperatures of the water and the object, the specific heat can be calculated using the principle of energy conservation.
