Examples of Intensive properties of a system are:
Correct answer: D. All of the above.
- A. Surface tension and Viscosity.
- B. Pressure and Density.
- C. Melting and Boiling points.
- D. All of the above.
Explanation
The correct answer is Option D: All of the above. Intensive properties are characteristics of a substance that do not change with the amount of the substance present. Surface tension, viscosity, pressure, density, melting point, and boiling point are all examples of intensive properties. They remain constant regardless of the system's size or extent. This distinguishes them from extensive properties, which depend on the system's size or the amount of matter present, such as mass and volume.

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.
