The standard heat of combustion of a hydrocarbon compound is an/a:
Correct answer: C. Intensive property
- A. Extensive property
- B. Colligative property
- C. Intensive property
- D. Constitutive property
Explanation
Standard heat of combustion is defined for a specific amount of substance (per mole). Since the property is defined per unit amount, it does not depend on the total quantity of the substance present, making it an intensive property.

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.
