Total heat energy (q) can be calculated in a bomb calorimeter by using following formula:
Correct answer: B. c x ∆T
- A. m x s
- B. c x ∆T
- C. s x ∆T
- D. c x s x ∆T
Explanation
In a bomb calorimeter experiment, the heat released by the reaction (q) is absorbed by the entire calorimeter assembly (bomb, water, etc.). The total heat absorbed is given by q = Ccal × ΔT, where Ccal (often written as 'c') is the total heat capacity of the calorimeter, and ΔT is the measured temperature change.

About Thermochemistry and Energetics of Chemical Reactions
Thermochemistry measures energy changes in chemical reactions and distinguishes exothermic from endothermic processes. Work covers systems, surroundings and state functions, internal energy, the first law of thermodynamics, enthalpy and Hess's law, including the sign conventions used when heat enters or leaves a system.
