Explanation
Calorimeter is the scientific instrument used to measure the quantity of heat.
A calorimeter is a device that is designed to measure the heat absorbed or released during a chemical reaction or a physical change. It works on the principle of the conservation of energy, which states that energy cannot be created or destroyed, but can only be converted from one form to another.
A typical calorimeter consists of an insulated container, a stirrer, and a thermometer to measure the temperature of the contents. The sample whose heat content is to be measured is placed in the container along with a known quantity of water. The sample is then heated, and the temperature change of the water is recorded.
The amount of heat absorbed or released by the sample can be calculated using the formula Q = mCΔT, where Q is the heat absorbed or released, m is the mass of the sample, C is the specific heat capacity of the water, and ΔT is the change in temperature of the water.
Calorimeters are used in a variety of fields, such as chemistry, physics, and engineering, to measure the heat of combustion, the heat of reaction, and the heat capacity of materials.
