The properties of the system, which are independent of amount of the material, are called:
Correct answer: B. Intensive properties.
- A. Extensive properties.
- B. Intensive properties.
- C. Physical properties.
- D. Chemical properties.
Explanation
The correct answer is Intensive properties. These are properties that do not depend on the amount of material present. Examples include temperature, density, and boiling point. This is in contrast to Extensive properties, such as mass and volume, which do depend on the quantity of material. Physical properties refer to characteristics that can be observed without changing the substance's chemical identity, and they can be either intensive or extensive. Chemical properties involve a substance's ability to undergo a chemical change and transform into a different substance, which is a different classification altogether.

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.
