How is density a more useful measurement than mass (or volume)?

Question

...also, is density a property of a material?

Answer 1

Density contains more information than mass or volume alone, making it more useful

density = mass/volume (which means density is the mass per unit of volume)

using density you can determine that A denser object will have less volume than an equal mass of some less dense substance.

Answer 2

The density of water is 1. Anything with a density less than one floats. Anything with a density more than one sinks. That is more important than how much it weighs, (mass), or how big it is, (volume). Since each material has a different density then it is reasonable to believe that the density is a property of the material unless you want to get legal talking about property rights or metaphysical or philosophical and talk about some other aspect.

Answer 3

it depends on the use but density is a better judgment of strength for one ( overall it is a better description of the physical properties of the material - think of describing a cubic foot of water 1. by weight **6-7 lbs 2. by volume**one cubic foot 3. by saying it has the density of water ( which is the best description )

density IS a property of a material but it is a variable property - water is less dense when cold (ice) metals are less dense when hot ( molten steel ) *****the only property that is permanent is mass - it stays the same no matter what state the substance is in ( unless you take some of the substance away or add to it the mass will not change )

Answer 4

Density is the amount of mass is a given volume, volume is the amount of space an object takes up, and mass is the amount of matter in an object. M / V = D (mass divided by volume = density)

Answer 5

Density is an inherent property of a substance at a given temperature--regardless of how much or how little of that object you might have, it density is always the same.

Mass and volume, however, change based upon the amount of the sample you have.

Answer 6

To get your volume, you'll want a bath with instantly aspects. Fill it adequate so as that you'll thoroughly immerse your self into it and mesaure how extreme the water rises. That shows how a lot you displace the water. Now, enable's say the bathtub is two meter by skill of one million meter and also you boost the water factor by skill of .25 meters (those figures are probable no longer even close), then your volume will be 2 * a million * .25 or .5 cubic meters. Get your weight (to make it effortless i will assume that you weigh 100KG) and divde that by skill of your volume or 100/.5 which grants 2 hundred kg/cubic meter. you could then get the density of the different elements (verify your physics books or do a glance for on the internet) and end your mission.

Answer 7

Well, it describes the proportion of weight to size. Mass is only weight, while volume is only size.

Yes, density is a property of metals. All metals are relatively more dense than other elements.

Answer 8

yes it is a property and volume chages, mass is depends on how big the object it, whereas density is per unit so it won't matter how big of small the object is
