density is a measurement of?

Answer 1

Medically a term used to measure bone mass. It is a measure of how much mass is contained in a given unit volume (density = mass/volume). It is usually expressed in kg/m^3. Put simply, if mass is a measure of how much ‘stuff’ there is in an object, density is a measure of how tightly that ‘stuff’ is packed together.
One of the ways we can see density illustrated in everyday life is by looking at whether things float or sink in a liquid (water, for example). If an object is less dense than the liquid it is placed in, it will float. If it is more dense, it will sink. This is why an anchor, which is very dense (lots of mass in a relatively small volume) sinks very quickly, while an inner tube (not much mass in a relatively large volume) floats and is very difficult to push underwater.

Some elements are naturally found in very dense forms, and one of the most surprising cases of a less dense object floating on a denser liquid occurs when objects are put in a container of liquid mercury (Hg). This element is a metal that is liquid at room temperature, and it is VERY dense. In fact, it is denser than lead, and metal objects like forks, coins, or even a cannonball will float on top of it!

Answer 2

Density is the measure of something per something. In math talk, we could write rho = A/B; where rho is a density variable, A is something that can be more or less dense (compacted), and B is the something into which A is compacted.

EXAMPLE: A = number of college students and B = one telephone booth. Therefore the student density in that telephone booth is rho = A/B = N/1; where N is the number of students and the 1 is the one telephone booth.

EXAMPLE: A = mass of a bowling ball and B = volume (4/3 pi r^3) of that ball. Therefore the mass density of that ball is rho = A/B = m/(4/3 pi r^3); where m is mass and r = radius of the ball.

There are all kinds of density: flux density, molar density, atmospheric density, weight density, population density, and on and on. But they all have one thing in common, they are the measure of something compacted into something (a volume, an area, a container, etc.).

Answer 3

Density

Answer 4

Mass per Volume.

It determines that how compact the particles of the substance are arranged. Solids have higher densities than liquids and liquids have higher densities than gases.

Answer 5

It is a way of measuring the amount of substance in an object per volume

Answer 6

denity is measurement of anything per unit area.
i:e
mass density=mass/unit area

Answer 7

Mass per volume

Answer 8

Mass per unit volume.

Answer 9

Mass per unit volume. So, you have to define your units: g/ml. kg/litre, tonnes per cubic metre, etc.

Answer 10

More or less of something. In all aspects.
