"Bomb Calorimetry"
How does the bomb calorimetry work? Got confused by what the different parts do and how they function as a whole.

Re: "Bomb Calorimetry"
A bomb calorimeter is a type of constant-volume calorimeter used in measuring the heat of combustion of a particular reaction.
Electrical energy is used to ignite the fuel; as it's burning, it will heat up the surrounding air, which expands and escapes through a tube that leads the air out of the calorimeter.

Re: "Bomb Calorimetry"
Bomb calorimeter involves measuring the heat of a fuel sample when burned under stable temperature to evaluate the heating energy of the fuel sample. The sample can be a solid or liquid, but not a gas.

Re: "Bomb Calorimetry"
A Bomb Calorimeter is a measuring tool to find the heat of combustion using an inner hard container to measure how a reaction reacts to an addition of energy into the system. The inner container is rigid and doesn't expand, hence the "bomb" portion of the name because it can hypothetically explode like a bomb. But the reaction is surrounded by water and a connecting piece that allows heat from the inner container to flow to the water and heat it up, which is measured by a thermometer.

Re: "Bomb Calorimetry"
A bomb calorimeter is similar to any other calorimeter as it measures the heat involved in a reaction, but unlike a constant pressure calorimeter which keeps a reaction at a constant pressure, a bomb calorimeter keeps a reaction at a constant volume. Like all calorimeters, a bomb calorimeter has a stirrer (to ensure even temperature distribution throughout the solution), a thermometer (to measure the energy lost/absorbed), and an insulated outer chamber. But to keep the volume fixed, a bomb calorimeter also needs a rigid inner chamber, an oxygen inlet to allow oxygen in in a controlled manner, and firing leads that are used to ignite a sample/reaction.
