$\Delta$E values obtained by bomb calorimetry can be converted to give accurate $\Delta$H values.

Question

Quizplus · Accepted Answer

This statement is true. The enthalpy change, ΔH, can be calculated using the equation ΔH = ΔU + PΔV, where ΔU is the internal energy change, P is the pressure, and ΔV is the change in volume. For a bomb calorimeter, ΔV is essentially zero, and thus can be ignored. Also, since the experiment is conducted at constant volume (no work is done), PΔV is also zero. Therefore, ΔH = ΔU, and the values obtained from a bomb calorimeter (ΔU) can be used to calculate ΔH.
