Can someone go into more depth of how the calorimeter works.

I was confused about the same thing, and I found this website helpful:
There isn't much emphasis on coffee cup vs. bomb calorimeters, but I think it helps with understanding generally the use of calorimeters.

To measure heats of reactions, we enclose reactants in a calorimeter, then we initiate the reaction, and then measure the temperature difference (before and after the reaction). The temperature difference allows us to evaluate the heat released in the reaction.

We use bomb a calorimeter to measure the change in Enthalpy at a constant volume (gas or solution). A coffee cup Calorimeter is used to measure the change in heat at a constant pressure (solution only).
