Question

Which of the following pairs is in intensive property?

• A. Density, viscosity
• B. Surface tension, mass
• C. Viscosity, internal energy
• D. Heat capacity, volume

Answer 1

Answer: (A)

Density, viscosity

Density, viscosity are intensive properties. Their magnitude is independent of the amount of matter present in the system. Other examples of intensive properties include temperature, surface tension, refractive index, melting point, boiling point and specific heat.
On the other hand, mass, internal energy and volume are extensive properties. Their magnitude depends on the amount of matter present in the system.
