Digital Bomb Calorimeter, A Bomb Calorimeter measures the amount of heat generated when matter is burnt in a sealed chamber in an atmosphere of pure Oxygen gas.A known amount of the sample is burnt in a sealed chamber (Bomb). The air is replaced by pure Oxygen. The sample is ignited electrically. As the sample is burnt, heat is produced. The rise in temperature is measured. Since barring the loss of heat, the amount of heat produced by burning the sample must be equal to the amount of heat absorbed by the Bomb Calorimeter assembly. A knowledge of the Energy Equivalent of the Bomb Calorimeter assembly and of the rise in temperature enables one to calculate the heat of combustion of the sample
