can someone explain what the difference between a regular calorimeter and a bomb calorimeter is?

In a regular calorimeter, the reaction takes place in the water. In a bomb calorimeter, the reaction takes place in a sealed metal container.

A bomb calorimeter is a closed system, meaning that matter cannot be exchanged with surroundings, but heat can. A coffee cup calorimeter is an isolated system, which means that no matter and no heat is exchanged with surroundings. Hope this helps!

Hi! The fundamental thing that you have to know is different between a bomb calorimeter and a normal calorimeter is that in a bomb calorimeter, the volume is held constant. This means that there is no work done in a bomb calorimeter, and therefore any change in the internal energy is dependant on the q value (at constant p) which is equal to the del H of the reaction.

In both a normal calorimeter and a bomb calorimeter, does q(sys) still equal -q(surr)?

For a bomb calorimeter, the volume is constant.

regular calorimeter=reaction takes place in the water, bomb calorimeter=reaction takes place in a sealed metal container.
