Question

Which of the following pairs is an intensive property?
A. Density, Viscosity
B. Surface tension, mass
C. Viscosity, internal energy
D. Heat capacity, volume

Answer 1

Hint: The intensive property can be defined as the property of the system that does not depend upon the quantity or the amount of material in the system.

Complete step by step answer:
We know that the definition of the intensive property which is as follow,
The intensive property can be defined as the property of the system that does not depend upon the quantity or the amount of material in the system.
From the above given options
Density & viscosity are independent of the quantity of the material in the system
Hence option(A) is correct.
Option (B) is not correct since the mass depends upon the quantity of the material of the system.
Internal energy also depends upon the quantity of the material and hence option (C) is also incorrect.
Volume also depends upon the amount of the material in the system, so option (D) is also incorrect.
So, the correct answer is “Option A”.

Note: The multiplication or the division of two or more extensive properties is an intensive property.
For example
$\text{Density = }\dfrac{\text{mass}}{\text{volume}}$
The density is an intensive property that does not depend upon the quantity of the material in the system whereas mass and volume are the extensive properties that are dependent upon the quantity of the material in the system.
