(N/A) Extensive property: An extensive property is a property whose value depends on the quantity or size of matter present in the system. Examples include mass,volume,internal energy,enthalpy,and heat capacity.
Intensive property: An intensive property is a property that does not depend on the quantity or size of matter present in the system. Examples include temperature,density,and pressure.
$A$ molar property,$\chi_{m}$,is the value of an extensive property $\chi$ of the system for $1 \ mol$ of the substance. If $n$ is the amount of matter,then $\chi_{m} = \frac{\chi}{n}$ is independent of the amount of matter.
Other examples include molar volume,$V_{m}$,and molar heat capacity,$C_{m}$. Consider a gas enclosed in a container of volume $V$ at temperature $T$ [Fig. $(a)$]. If we introduce a partition such that the volume is halved,each part [Fig. $(b)$] now has one half of the original volume,$\frac{V}{2}$,but the temperature $T$ remains the same.
Therefore,it is clear that volume $V$ is an extensive property and temperature $T$ is an intensive property.
