Question

In thermodynamics, which one of the following properties is not an intensive property?
A. Pressure
B. Temperature
C. Volume
D. Density

Answer 1

Hint: We have to remember that the materials and systems physical properties are categorized by either intensive property or extensive property. When the size (or extent) of the system is changed the property (intensive and extensive) of the system changes.

Complete step by step answer:
We can divide the thermodynamic properties into two categories, they are intensive property and extensive property.
Now we discuss about intensive property as,
We have to remember that the intensive property does not depend on the amount of the substance present in the system and it depends only upon the nature of the substance present in the system. The intensive property, to describe the state of the system as used as variables at often.
For example molality, pressure, refractive index, temperature, density, melting point and boiling point, surface tension, specific heat, color, specific rotation, concentration, magnetic permeability, specific internal energy etc.
Now we can see the details of extensive property as,
We have to know that an extensive property depends on the quantity of matter contained in the system. For example heat capacity, volume, mass, energy, length etc. The quantity of matter and the size of the system is changed then these properties are changed. For the sake of convenience, the total value of property is equal to the sum of the separate parts into the system may be divided.
Option C. Volume is the correct answer. Because the volume depends on the quantity of the matter present in the system.

So, the correct answer is Option C.

Note: By specifying the unit of the amount concerned, an extensive property may become intensive property. Thus heat capacity is an extensive property but the specific heat is intensive, density is intensive property but mass and volume are extensive property.
