Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Density is one of the properties of a substance. How is the property classified?
A
Physical and intensive
B
Physical and extensive
C
Chemical and intensive
D
Chemical and extensive
Explanation: 

Detailed explanation-1: -Density is an intensive property because there is a narrow range of densities across the samples. No matter what the initial mass was, densities were essentially the same. Since intensive properties do not depend on the amount of material, the data indicate that density is an intensive property of matter.

Detailed explanation-2: -The density (d) of a substance is an intensive property that is defined as the ratio of its mass (m) to its volume (V). Considering that mass and volume are both extensive properties, explain why their ratio, density, is intensive.

Detailed explanation-3: -Density is the ratio of mass and volume of a substance and thus is a physical property of matter as it is not related to potential chemical changes in the substance. It also does not depend upon the amount of material and so is an intensive property since it is the ratio of two extensive properties.

Detailed explanation-4: -Density is a physical property of matter that expresses a relationship of mass to volume. The more mass an object contains in a given space, the more dense it is.

Detailed explanation-5: -Mass and volume are examples of extensive properties.
