Chemistry 11 Some Basic Concepts of Chemistry How to calculate the molar mass? Explanation: As the name suggests, molar mass is the mass of one mol

An intensive property is a bulk property, meaning that intensive property is a physical property of a system that does not depend on the system size or the amount of material in the system.

Examples of intensive properties include the temperature(T), refractive index (n), density, and hardness of an object.

When a diamond is cut, the pieces maintain their intrinsic hardness (until their size reaches a few atoms thick), which means hardness is independent of the size of the system.

By contrast, an extensive property is an additive for subsystems. This means that the system could be divided into any number of subsystems, and the extensive property measured for each subsystem; the value of the property for the system would be the sum of the property for each subsystem.

For example, both the mass and the volume, of a diamond are directly proportional to the amount that is left after cutting it from the raw mineral. Mass and volume are extensive properties, but hardness is intensive.

Option B is correct, Physical property of a system that does not depend on the system size or the amount of material in the system.
