Question

hat 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.

Answer 1

Correct answer: "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."

Brief explanation: a bomb calorimeter is a sealed, constant-volume vessel (the "bomb") used for combustion or reactions that aren't in solution; it measures heat by the temperature change of the surrounding water jacket. A coffee‑cup calorimeter is an open (or nearly open) constant‑pressure device used for reactions in aqueous solution, so it is limited to processes that occur in water.
