Does the density of a material depend on its size?

Question

Please answer this question and explain it to me.

thanx

Answer 1

Density is the mass of the object divided by its volume. If you change the size of a given amount of stuff, the density will change. If you cut an object in 2 pieces, each would still have the same density.

Answer 2

Density is defined as weight per unit volume. This means that weight and size are used to calculate a material's density.

density = weight / volume

Nevertheless, density is a property of the material and the fact that I have more or less of it does not effect the material's density.

Sometimes density is determined by weighing an object in air and dividing by the weight lost when weighed in water. (see, Archimedes)

Specific gravity = air weight / (air weight - water weight)

Once specific gravity is known, the object's density can be found by multiplying by the density of water. (63.5 lbs/cu. ft., or 1 g/cm^3)

Object's density = object's specific gravity(water's density)

Notice that this technique does not require you to measure the size of the object. Again, density is a property of the material, independent of its actual size.

Hope this helps........

Answer 3

Density of a material has to do with the materials make-up not how much material there is. Below let a piece =one cubic inch.
A sponge for instance is very porous. as there are many air pockets in it. A piece of balsa wood is also very porous. But it is much denser than sponge. A piece of Oak wood is less porous but is denser than the balsa wood. And a piece of steel is even more dense. From all of this we might say that the denser the object the more it weighs.

Answer 4

Density is an extrinsic property and does depend on its physical state (such as solid/liquid/gas). However, increasing or decreasing the size of an object would not change the density. Density is a property of the material itself, not the size of the material.
