Apparatus


Calorimeter cross-section
An adiabatic bomb calorimeter has the metal bomb inside of a metal bucket containing water. That metal bucket sits loosely inside an insulated jacket. There is a stirrer that sticks into the water in the bucket and is driven by a motor outside of the calorimeter. A thermometer also sticks into the water in the bucket and is the device that will be used to determine the change in temperature during the reaction. Two electrical leads connect to the top of the bomb from outside and they will deliver the current that initiates the reaction.

Bomb cross-section
The metal bomb provides a constant-volume system in which the combustion will reaction take place. The sample pellet is placed in the ignitiona cup and the fuse wire is carefully arranged to touch the pellet but not the cup. The bomb is sealed by screwing the cap on and then filled with a high pressure of pure oxygen. The electrical connections are made at the top and the bomb is placed into the water bucket.
