Why the density of a given pure substance remains constant regardless of the amount of material?
Wiki User
∙ 13y ago
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.

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.

∙ 14y agoThere 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).

∙ 13y agoDensity 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 .

∙ 12y agoDensity 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

∙ 9y agoWell . . . 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.
Wiki User
∙ 13y agoThis is because their ratio will stay the same (volume divided by mass = density).
Wiki User
∙ 14y agoDensity 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.
Wiki User
∙ 13y agoDensity 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.

Is density an intensive property or extensive property?
Density is an intensive property because it does not depend on the amount of substance being measured. It remains constant regardless of the quantity of the material present.
Would the density of a piece of gold be different depending on its size?
No, the density of gold remains constant regardless of its size. Density is a physical property of a substance that is determined by its mass and volume, so as long as the material remains the same, the density will also remain constant.
Why is density is a useful physical property for identifying substances?
Density is useful for identifying an unknown material because it is a physical constant. A physical constant is a unique characteristic of the material in question. This constant never change or vary with the shape or amount of the material/substance.
What are the usefulness of density in identification of unknown substance?
Density can help identify an unknown substance by comparing its measured density to known values for different materials. Substances have unique densities due to their composition and structure, allowing for classification based on this property. By determining the density of an unknown substance and comparing it to reference values, one can begin to narrow down potential identities.
Does changing the volume of a particular substance change its mass to volume ratio?
No, changing the volume of a substance does not alter its mass to volume ratio. The mass to volume ratio, also known as density, remains constant regardless of the volume of the substance. Density is a physical property that is intrinsic to the material and is not affected by changes in volume.
Will the density of a material always be the same regardless of it's size?
No, the density of a material remains constant regardless of its size. Density is an intrinsic property of a substance, defined as mass per unit volume. Thus, even if the size of an object changes, its density will remain the same as long as the material composition stays constant.
What happens to the density of a given substance if you increase the amount of substance that you have?
The density of a substance remains constant regardless of the amount of the substance. Density is an intrinsic property of a material and is determined by its mass and volume. Increasing the amount of substance will only change the mass and volume proportionally, thus keeping the density constant.
Why are mass and volume not characteristic properties but the density of a material is?
Mass and volume can vary depending on the size or amount of a substance, while density remains constant for a specific material. Density is a characteristic property because it is unique to each substance and helps identify the substance regardless of its mass or volume.
Does a density of the same substance vary or not?
No, the density of the same substance does not vary. Density is a physical property of a substance that remains constant regardless of the amount or volume of the substance.
Would 100G of soap have the same density as 200G of soap?
No, density is a property of a substance that remains constant regardless of the amount of the substance. Therefore, 100g of soap would have the same density as 200g of soap as long as they are made of the same material.
What is the density of a big object vs the smaller object of the same material?
The density of both objects will be the same regardless of their size if they are made of the same material. Density is a physical property of a material that remains constant regardless of the object's size or shape.
Is density an intensive property or extensive property?
Density is an intensive property because it does not depend on the amount of substance being measured. It remains constant regardless of the quantity of the material present.
Would the density of a piece of gold be different depending on its size?
No, the density of gold remains constant regardless of its size. Density is a physical property of a substance that is determined by its mass and volume, so as long as the material remains the same, the density will also remain constant.
Why does the density of an object stay the same for different amounts of the object?
Density is an intrinsic property of a material that remains constant regardless of the sample size. This is because density is defined as the mass of a substance per unit volume, so as long as the composition of the material and its volume remain constant, the density will not change.
Does 100 grams of something have the same density as 200 grams of the same matter?
Yes, density is an intrinsic property of a material and remains constant regardless of the amount of the substance. So 100 grams of a substance will have the same density as 200 grams of the same substance.
What effect does size have on the density of objects made of the same materials?
Size does not have a significant effect on the density of objects made of the same material. Density is an intrinsic property of a substance and is constant regardless of the size or shape of the object. However, larger objects made of the same material will have more mass and volume, but their density remains the same.
Why is density is a useful physical property for identifying substances?
Density is useful for identifying an unknown material because it is a physical constant. A physical constant is a unique characteristic of the material in question. This constant never change or vary with the shape or amount of the material/substance.
