Question

A bomb calorimeter operates at constant volume. What thermodynamic quantity does it directly measure?
Options
A Enthalpy change (ΔH)
B Internal energy change (ΔU)
Correct Answer
C Pressure-volume work (w)
D Gibbs free energy (ΔG)
Correct Answer

Option B is the correct answer.

Detailed Explanation

Because volume is held strictly constant (ΔV = 0), w = 0, and the heat measured directly equals ΔU.
