### Bomb calorimeter

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!

### Re: Bomb calorimeter

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.

### Re: Bomb calorimeter

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.
