Explain extensive property and intensive property.

Explanation

Extensive property : An extensive property is a property whose value depends on the quantity or size of matter present in the system. e.g., mass, volume, internal energy, enthalpy, heat capacity, etc.
Intensive property : Intensive property is those properties which do not depend on the quantity or size of matter present
e.g., temperature, density, pressure etc.
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, `chi_(m) = (chi)/( n)` is independent of the amount of matter.
Other examples are molar volume, `V_(m)` and molar heat capacity, `C_(m)`. Take a gas enclosed in a container of volume V and at temperature T [Fig. (a)). Let us make a partition such that volume is halved, each part [Fig. 6.6 (b)]

Now has one of the original volume `{:(V),(2):}`, but the temperature will still remain the same.
Therefore, it is clear that volume V is an extensive property and temperature T is an intensive property.
