What explains the key difference between a bomb calorimeter and a coffee cup calorimeter? a bomb calorimeter is 10 times larger but works the same way. a bomb calorimeter measures heat for liquid products only. a bomb calorimeter has a separate chamber to hold substances and can even measure heat gain or loss for reactions that do not occur in water. a bomb calorimeter can measure heat gain or loss in gaseous reactions but is not useful for reactions that occur at high pressures and temperatures.
