Can someone explain what a bomb calorimeter does? Thanks in advance.

I don’t think we need to know the actual mechanics and details about the calorimeter. However, it’s important to know that the calorimeter essentially measures the change in temp of the solution/mixture inside the bomb calorimeter. The bomb calorimeter allows us to determine the q (heat transfer) of the solution/ mixture. From q value of the inside solution/mixture, we are able to compute the q of the calorimeter itself, which is just the negative value of the q value.

I believe all you need to know about a bomb calorimeter is that it is used to measure the temperature of a combustion reaction and that it would be considered a closed system.

I think it might actually be an isolated system as you do not want the heat escaping in order to measure the heat of the reaction occurring in the calorimeter.

I think it was just important to know that the constant V (calorimetry) is associated with it. The problems will say something like "In a constant P calorimeter," so I doubt we'll have to know exactly how it works.

According to the notes, a bomb calorimeter is an isolated system because nothing is exchanged with the surroundings!
