Explanation
-
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 the hardness of an object.
-
When a diamond is cut, the pieces maintain their intrinsic hardness (until their size reaches a few atoms thick), that mence hardness is independent of the size of the system.
-
By contrast, an extensive property is 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.
Correct Option is: (B)
Physical property of a system that does not depend on the system size or the amount of material in the system.
