Book Free Demo1. With the help of a neat diagram, explain the working of a calorimeter.
A calorimeter is an instrument is used to measure the amount of . It contains a vessel made up of , of heat and electricity.
Calorimeter:
The metallic vessel is placed in an jacket . There are two holes in the vessel. A thermometer is inserted through one hole to measure the of the materials. Through another hole, a stirrer is inserted to stir the content inside the vessel. The liquid filled inside the vessel is . Using calorimeter, we can measure the of the liquid in the container.
Working:
In a calorimeter, two forms of matter (generally solids and liquids) with different temperatures are made to be in physical contact with one another. Due to this temperature difference, the heat is transferred from . This process of heat transfer continues until the.
The principle of calorimetry indicates the . It means that the total is equal to the total .
The amount of heat transfer is calculated by the formula,
The unit of heat transfer is .
