What pressure of oxygen is maintained inside the bomb calorimeter?
Correct answer: C. 20 atm
- A. 200 atm
- B. 25 atm
- C. 20 atm
- D. 75 atm
Explanation
High-Pressure oxygen is required to ensure the sample burns completely in the bomb vessel. The oxygen assists with the burning of the sample to ensure the sample burns completely for an accurate final result.The Federal Book says 25 atm, while PTB says 20 atm.

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.
