Ignition coil in bomb calorimeter
Correct answer: C. Pt
- A. C
- B. Fe
- C. Pt
- D. Cu
Explanation
In a bomb calorimeter, the ignition coil is typically made of platinum (Pt). Platinum is chosen for this purpose because it is resistant to corrosion and oxidation at high temperatures, ensuring that it remains functional over multiple experiments without degrading. Additionally, platinum has a high melting point, which allows it to withstand the heat generated during the combustion process without deforming or melting.

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.
