Density
Density is mass per unit of volume. Density also shows how tightly packed in molecules are in a material and also help determine buoyancy.

A material with a density of 1.0 g/cm3 is typically water at room temperature. This means that 1 cubic centimeter of water has a mass of 1 gram.
What is the density of feathers?
Feathers have a relatively low density compared to many other materials, ranging from about 0.2 to 0.8 grams per cubic centimeter, depending on the specific type of feather.
Density is a measure of how much mass is contained in a given volume. It is calculated by dividing an object's mass by its volume. Denser objects have more mass packed into a smaller space, while less dense objects have less mass in the same volume.
The density of an egg varies based on factors like its size, age, and species. Generally, eggs have a density close to that of water, typically ranging from 1.03 to 1.12 grams per cubic centimeter. The denser portion of an egg is the egg white, while the yolk is less dense.
How do you find the density of an object without finding its mass?
The speed of sound through an object is related to the density and elasticity of the material. Velocity = square root of (elasticity (bulk modulus) divided by density). Thus if you can measure the material's elasticity and the velocity of sound waves passed through it, the density can be calculated without reference to the mass of the object.
How do you you find the density of an object by comparing it to another known density of a solution?
If your experiment shows that your unknown material has twice the density of your known material, you can simply look up the density of the control material and double it (or multiply by whatever the ratio is). This will give you the density of the unknown and you can attempt to identify it by looking for this number in a density table.
What is the density of styrofoam?

EPS can be ordered to many different weights. In the US, it is commonly ordered as "2Llb EPS" meaning 2lb per FT³. I have ordered it as low as 1lb/ft³ and as high as 5lb/ft³. I forget exactly how dense you can order it. Try calling a local EPS supplier like insulfoam.
To change density there are three ways. You can change the shape, mass or volume of the object
When is it helpful to use density?
If you do not know which material you have, knowing the density can help you identify it. Examples: Solid - water - noble gas
Copper has a density of 8950 kg/m3 = 8.95 kg/dm3 = 8.95 g/cm3.
Water has a density of 1000 kg/m3 = 1000 g/L = 1.000 kg/dm3 = 1.000 kg/L = 1.000 g/cm3 = 1.000 g/mL.
Helium has a density of 0.1785 kg/m3 = 0.1785 g/L = 0.0001785 kg/dm3 = 0.0001785 kg/L =
0.0001785 g/cm3 = 0.0001785 g/mL.
The crushed can will have a density that is quite a bit higher than the density of the can before it was crushed. Imagine a box of empty aluminum beverage cans. It won't weigh much. If those same cans are crushed, they will weigh the same, but take up a lot less space. The density of the cans can be increased by crushing them. The cans might be said to have a low bulk density before being crushed.
What the formula for relative density?
The relative density of a substance is the ratio of its density to the density of some standard substance. The standard substance for solids and liquids is water. Thus for solids or liquids: Relative density = denisty of substance (kg/m3) / density of water (kg/m3) Relative density therefore has no units, it is a number, and indicates only how many times more dense the substance is than water. The relative density of water is 1 or 1000 kg/m3.
What is the Density of concrete?
- Density of normal concrete is in the order of about 2400 kg. per cubic metre. The densityof light-weight concrete will be less than about density 1900 kg per cubic metre.
- The high density concrete have unit weight ranging from about 3360 kg percubic metre to 3840 kg per cubic metre.
What is the formula for the density of a cylinder?
The density of an any material/object is given by p=m/V
The volume of a cylinder is V= πr2h
So the density of a cylinder is therefore: p=m/πr2h
Where: m is mass, r is radius and h is the height of the cylinder.
What is the formula to finding density?
The formula for calculating density is as follows: density = mass/volume. Simply put, if you divide an object's mass by its volume, you will find its density. Density is the mass of an object per unit volume.
The density of wood is 650 kg/m3.
That depends on the species of wood. Balsa is very light, D ~ 0.2. Other woods are more dense. Any that float in water have a density less than 1. If it sinks the density is greater than 1.
Density is the mass of the object divided by the volume of the object.
D=m/V
Ether is the common name for the compound, diethyl ether. It has the chemical formula of (C2H5)2O. As a liquid, its density is .7134 grams per cubic centimeter.
The density of tea can vary depending on the type and preparation method. On average, brewed tea has a density of about 1.0 g/cm^3, which is close to the density of water. However, other factors like sugar content, additives, or temperature can affect the density of tea.
What is the density of a cylinder?
Density = Mass/Volume, correct. However, with a cylinder, you have to find the volume. In order to find the volume of a cylinder use the equation PiR2 * H where "R" is the radius (Diameter/2) squared.
