Why the density of a given pure substance remains constant regardless of the amount of material?

Answer 1

Density represents mass per volume and so when homogeneous (and incompressible), an amount increase/decrease does not change density, as the mass and volume change in the same proportioning. Water density is 8.34#/cu ft, whether it is 2 cubic feet or 4 cubic feet.

Answer 2

The density of a pure substance remains constant regardless of the amount of material because density is an intrinsic property of the substance that is defined by the relationship between its mass and volume. As you increase or decrease the amount of material, the mass and volume both change proportionally, resulting in a constant density value. This is because density is a measure of how tightly packed the particles of a substance are, and this arrangement remains consistent regardless of the quantity of the substance.

Answer 3

There are probably several other constant ratios in everyday life that are no problem for you.

Examples:

Whether you buy one newspaper or a hundred, the unit cost (cost per copy) is a constant for that publisher.
It's always
(total cost of all the newspapers) divided by (the number of newspapers you buy).

Whether you go on a long trip or a short trip, the speed (miles per hour) is a constant for that driver.
It's always
(total distance you drive) divided by (time the trip takes to drive).

Whether you eat a small helping or a bowlful, the caloric content (calories per serving) is a constant for that food item.
It's always
(total calories in the amount you ate) divided by (number if servings in that amount).


Whether you have a large sample or a small sample, the density (mass per unit volume) is a constant for that substance.
It's always
(mass of the sample) divided by (volume of the sample).

Answer 4

Density of substances remain the same because both the mass and the volume decrease which is directly propotional to the density of the substance and taken to cut it into pieces due to which the density remains the same .

Answer 5

Density is equal to the mass per unit of volume. So if you add more of that substance, you are increasing both the volume, and mass of the substance. For example let's say I have 1kg of a substance which just do happens to fill 1L of a container. This means the density of the substance is 1/1 which is 1. Now if I increase the mass to 2kg, the volume will also increase because of the addition. This means that I now have 2kg in 2L which is 2/2 which is 1. So increasing the mass does not actually change the density

Answer 6

Well . . . the density of a substance does change slightly due to temperature and pressure changes.

Otherwise, the density of a substance will stay close to the same because the substance is physically stable . . . there is not much that can significantly change its density.

Answer 7

This is because their ratio will stay the same (volume divided by mass = density).

Answer 8

Density is the ratio between mass and volume as mass increases the volume also increases in the same ratio so density for every pure substance at any given temperature is always constant.

Answer 9

Density is mass per unit volume and is a characteristic of a substance. When the amount of material is changed, the mass and volume change in proportion so that the density remains constant.
