calorimeter

[Saachi_Kotia_4E]

can someone explain how calorimeters and bomb calorimeters work? I dont really understand the explanation in the textbook. what do they do and what are we trying to calculate when doing problems?

I think the whole point of the calorimeter is to have a reaction that doesn't lose energy or matter as it happens, so it basically isolates heat and doesn't release any gases produced in the reaction. I don't understand what the bomb calorimeter is exactly either though.

A calorimeter measures the heat capacity of a substance under either unchanging volume or unchanging pressure.
