Per NCERT §5.3, a BOMB CALORIMETER measures which thermodynamic quantity?
ABond enthalpy directly
Bq_V = ΔU (heat at constant volume, since the bomb is sealed and ΔV = 0)
Cq_p = ΔH
DSpecific heat alone
Answer & Solution
Correct answer: B. q_V = ΔU (heat at constant volume, since the bomb is sealed and ΔV = 0)
Per NCERT §5.3(a), bomb calorimeter = constant V → q_V = ΔU. Constant-p calorimeter gives ΔH.
