Which from following is an example of an intensive property of the system?

  • A
    Volume
  • B
    Enthalpy
  • C
    Entropy
  • Correct answer
    D
    Molar volume

Solution

Intensive properties remain invariant with respect to the quantity of substance, while extensive properties scale proportionally with the amount.

Volume is extensive, as it increases with the quantity of matter.
Enthalpy and entropy are both extensive thermodynamic quantities dependent on system size.

Molar volume, defined as $v = V/n$, represents the ratio of two extensive properties.
This quotient yields an intensive property, as demonstrated by the constant molar volume of substances like water under fixed conditions.

The intensive property is molar volume.

Hence, the correct answer is option: 'D'.
