One Calorie is equal to:
Correct answer: B. 4.18 J
- A. 4.18 kJ
- B. 4.18 J
- C. 0.418 KJ mol-1
- D. 0.418 KJ
Explanation
1 calorie equals 4.18 J. It is very often confused with 1 kcal, which equals to 4.18 kJ

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.
