# Is Density Intensive: How, Why and 7 Facts You Should Know

In this article, the topic, “Is Density Intensive” will be discuss with How, Why and other 7 relevant facts. Intensive property explained as, the property of a matter or system does not figure on mass.

Intensive property for a substance is, the characteristics which are not lie on the size of the amount of the substance. The density of a liquid substance is not changes during the changes of its size or quantity of the liquid substance thus we could clearly say that density of a substance is an intensive property.

The other examples of the intensive property are listed in below section,

1. Temperature (T)
2. Pressure (P)
3. Surface tension
4. Viscosity
5. Specific heat capacity cp
6. Chemical potential
7. Electromotive force
8. Thermal conductivity
9. Specific internal energy (u)
10. Melting point
11. Magnetic permeability
12. Standard reduction potential E0
13. Specific rotation (a)
14. Refractive index
15. Concentration

## How is density intensive?

Density for a substance can be explained as, mass of a unit volume.

The density of substance is not depending upon the changing of mass of a substance. The density remains constant in changing of mass of a matter. Since the property of intensive also remains unchanged changing of mass of a matter. The density not depends on the shape and size of any matter.

The formula density of a substance is can be written as,

ρ=M/V

Where, ρ is express as density of a substance, M is express as mass of a substance and V is express as volume of a substance.

The unit of the density in S.I. unit is, Kilogram per cubic meter.

## When is density intensive?

A system property can be divided in two sections, one is intensive and another is extensive, foundation on the physical nature dependency.

Density called as intensive property because a small limit is present of densities across the specimens. Density of a matter is not depending upon the size, shape and quantity of a matter. The physical quantity of intensive also does not depend on the shape, quantity and size of the matter.

Another thing we can observe that the ratio of two any type of extensive property made intensive property. Such as, the proportion of Mass and Volume is equal to the density. Mass and volume both are extensive but their proportion density is intensive.

Mass/Volume = Density

## Is mass density intensive or extensive?

Yes, mass density intensive.

The density ρ of some liquid and solid substance are listed below,

1. Density of water is 1000 kilogram per cubic meter
2. Density of steel is 7750 – 8050 kilogram per cubic meter
3. Density of concrete is 2400 kilogram per cubic meter
4. Density of air is 1.2 kilogram per cubic meter
5. Density of hydrogen is 0.0898 kilogram per cubic meter

### Difference between intensive and extensive:-

The major difference between the intensive property and extensive property are listed below,

## How is mass density intensive?

Mass density can be explained as, the quantity of mass of a system or substance, object or material in contacts to the circumstance is occupies.

The ratio of two any type of extensive property made intensive property. Such as, the proportion of Mass and Volume is equal to the density. Mass and volume both are extensive but their proportion density is intensive since the mass density is an intensive property.

The mass density of substance is not depending upon the changing of mass of a substance. The density remains constant in changing of mass of a matter. Since the property of intensive also remains unchanged changing of mass of a matter. The mass density not depends on the shape and size of any matter.

The several terms for the mass density are volumetric mass density, density and specific mass. The mass density depends on some facts such as, pressure and temperature.

A gaseous substance is increasing its volume when excess amount of heat is absorbed by the substance and temperature is increasing. We know that, Mass/Volume = Density that’s mean when the volume of a gaseous substance is increases the density is decreases and when the volume of a gaseous substance is decreases the density is increases.

## Is vapour density intensive or extensive?

Vapour density can be explained as; mass of a particular substance’s volume is divided by the mass of equivalent volume of hydrogen. Vapour density is, the density of a vapour in connection to that of hydrogen.

Vapour density is an intensive property. Vapour density of a matter is not depending upon the size, shape and quantity of a matter it is an independent physical characteristics. The physical quantity of intensive also does not depend on the shape, quantity and size of the matter for this reason; vapour density is clearly an intensive property.

The formula for the vapour density is,

Vapour density =Mass of n molecules of gas/Mass of n molecules of hydrogen

Vapour density = Molar mass of gas/Molar mass of H2 vapour density= Molar mass of gas/ 2.016 vapour density= 1/2 *Molar mass

(And thus: molar mass

× vapour density)

For example, vapour density of mixture of NO2and N2O4 is 38.3.

## Is change in density point intensive?

The density of a matter can be differing for the reason of changing of pressure or changing of temperature. Increasing the pressure density increases and increasing of temperature density decreases.

Yes, change in density point is intensive. Change in density point of a matter is not depending upon the size, shape and quantity of a matter it is an independent physical characteristics. The physical quantity of intensive also does not depend on the shape, quantity and size of the matter for this reason; vapour density is clearly an intensive property.

Heating a matter can causes the molecules of the matter speed up and spread slightly further apart, assuming a larger volume that results in a decrease in density.

## Conclusion:

Yes, density is an intensive property. Density is an independent property of a physical matter it does not depend upon the quantity, size and shape of the matter. Density cannot be calculated same as the intensive property cannot be calculate.
