Which among the following pair of properties are intensive?
Which among the following pair of properties are intensive?
surface tension and viscosity
mass and temperature
internal energy and boiling point
heat capacity and specific heat
Solution
The correct answer is (1) surface tension and viscosity.
Intensive properties are properties that do not depend on the amount or size of the substance, and remain the same regardless of the quantity of the material present. On the other hand, extensive properties depend on the amount of substance.
- Surface tension and viscosity are both intensive properties because they are independent of the amount of substance. Surface tension measures the cohesive force at the surface of a liquid, while viscosity measures the resistance of a liquid to flow. Both are properties that remain constant regardless of the amount of liquid.
