Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The density of pyrite is 5g/cm3 . This is an example of
A
intensive property
B
extensive property
C
chemical change
D
chemical property
Explanation: 

Detailed explanation-1: -Density is an intensive property of matter that illustrates how much mass a substance has in a given amount of volume.

Detailed explanation-2: -Density is an intensive property of matter that illustrates how much mass a substance has in a given amount of volume.

Detailed explanation-3: -Examples of intensive properties include temperature, T; refractive index, n; density, ; and hardness, . By contrast, extensive properties such as the mass, volume and entropy of systems are additive for subsystems.

Detailed explanation-4: -Density as Intensive Property. Density is the ratio between the mass of a sample and its volume. Since it is a ratio, it will always be the same regardless of how much of the sample it measured. When a property, like density, is independent of the amount of sample measured, it is known as an “intensive” property.
