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.
