Which of these is an extensive property of a substance?

color

hardness

malleability

volume

is an extensive property of the substance.

Further Explanation:

The property is a unique feature of the substance that differentiates it from the other substances.

Classification of properties:

1. Intensive properties:

These are the properties that depend on the nature of the substance. These don't depend on the size of the system. Their values remain unaltered even if the system is further divided into a number of subsystems. Temperature, refractive index, concentration, pressure, and density are some of the examples of intensive properties.

2. Extensive properties:

These are the properties that depend on the amount of the substance. These are additive in nature when a single system is divided into many subsystems. Mass, energy, size, weight, and length are some of the examples of extensive properties.

Color

Color of the substance does not depend on the amount of matter that is present in the substance. So it is an intensive property.

Hardness

Hardness is independent of the quantity of matter contained in any substance and therefore, it is an intensive property.

Malleability

Malleability is defined as the physical property of a substance, generally a metal due to which it can be deformed under pressure. Any malleable metal can be converted into thin sheets by applying compressive stress to it. It depends on the nature of the substance and not on its quantity. So malleability is an intensive property.

Volume

Volume is the quantity of space that is occupied by any substance, be it a solid, liquid or gas. Quantity of space occupied depends on the amount of the substance so volume is an extensive property.
