<h3>What is a bomb calorimeter?</h3>
The bomb calorimeter is used to obtain the energy of a sample. This is called the energy equivalent or the energy value of the sample.
Now, we know that the bomb calorimeter is calibrated by the use of benzoic acid hence it must be combusted first to obtain the basic energy value of the calorimeter.
