Those physical properties which are not affected by the amount of matter present in a substance are called size-independent properties. Melting point, boiling point, and density are some examples of size-independent properties.

2 size independent properties = conductivity, bowing point, state of matter, and melting point.

Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present. Physical properties can be measured without changing a substance’s chemical identity.

Mass is a size- dependent property of a given substance because its value depends on the size of a sample. Mass is an amount of matter in something. Weight is the pull of gravity on that matter. Weight changes with location, but mass does not.

The extensive properties are defined as the properties which depends on the amount of matter present. Examples are volume, mass, internal energy etc. From the options give below, temperature, viscosity & molar heat capacity are intensive properties while internal energy is an extensive property.

Examples of extensive variables include the volume, mass, and total energy. If an extensive variable is divided by an arbitrary extensive variable, such as the volume, an intensive variable results. A macroscopic system can be described by one extensive variable and a set of intensive variables.

Pressure being defined as force per unit area, does not vary with the change in the size of the substance. 2. Density is also an example of intensive property as it depends on mass and volume, which themselves are extensive properties.

Temperature, refractive index and viscosity are independent of the amount of matter present in the system. Hence, these are intensive properties.

Temperature remains intensive through- out the system. This occurs even though surface properties, like surface area and luminosity, are not extensive, while bulk properties, like mass and volume, are extensive.

Solution(By Examveda Team) Since refractive index is not dependent on the amount it is not an extensive property.

Extensive properties depend on the amount of matter present, for example, the mass of gold. Intensive properties do not depend on the amount of matter present, for example, the density of gold. Heat is an example of an extensive property, and temperature is an example of an intensive property.

So doubling the mass of an object doubles its heat capacity, but does not change its specific heat capacitance.
