Hi Rani


A bomb calorimeter is basically a thick-walled steel container used to determine the energy contained in a substance by measuring the heat generated during its combustion and is used to measure heat flow for solids with low to high temperature reactions.

Whereas ,

A coffee cup calorimeteris a constant pressurecalorimeter .A coffee cup calorimeter is great for measuring heat flow in a chemical solution, but it can't be used for reactions, which involve gases since they would escape from the cup .


Thankyou
