Vedclass · Answer

(C) bomb calorimeter is a constant-volume calorimeter used to measure the heat of combustion of a substance. Since the volume is kept constant $(dV = 0)$,the work done is zero $(w = -P_{ext} \Delta V = 0)$. According to the first law of thermodynamics,$\Delta U = q + w$. Since $w = 0$,the heat measured $(q_v)$ is equal to the change in internal energy,$\Delta U$ (or $\Delta E$).

The amount of heat measured for a reaction in a bomb calorimeter is
