Understand Bomb Calorimeter. Click on the link to Watch the VIDEO explanation: Watch Video
For reactions involving gasses such as combustion we use a device called bomb calorimeter. The calorimeter has a water filled insulated box inside which is heart of calorimeter the bomb. The bomb is strong steel container in which exothermic reaction is carried out at near explosive rate and the reactant and product of confine to constant volume. The reactant sample of known mass is taken in a metal cup in the bomb. The bomb is then filled with oxygen at a pressure of 30 atmospheres. The reacted is initiated with an electric ignition wire. Stirrer is used to maintain the constant temperature. The heat of reaction is determined from the temperature rise in the water that surrounds the bomb. The highest temperature recorded by the thermometer is noted. The internal energy change delta E of the combustion reaction is determined using the equation. And the formula as shown there where means, Z=Heat capacity of calorimeter system, T=Rise in temperature M= Molecular Mass of substance W=Mass of substance taken.
