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.

Unit for density?

volume per mass or volume/mass. Ummm can anyone check up the word rho i think that is the unit!!!

What is the density of oak?

The density of oak wood can vary depending on the species, but on average it is around 0.75 grams per cubic centimeter.

What is density used for?

Density is used to describe how much mass is packed into a certain volume. It is used to identify and compare materials, calculate buoyancy, determine purity of substances, and predict behavior of objects when interacting with other materials.

Density of Hydrogen?

Gaseous hydrogen has a density of 0.08988 g/cm. Liquid and solid hydrogen have a density of about 0.07 g/cc

At standard temperature and pressure (stp), hydrogen as a gas has density 0.08988 grams per litre. Hydrogen atoms have atomic mass of 1, and diatomic hydrogen molecules have molecular mass of 2. From this we can tell that hydrogen is the lightest (least dense) element in the periodic table.

What has its own density?

Each material has its own density!

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.

Density of methanol?

The density of methanol at room temperature (20°C) is about 0.7918 grams per cubic centimeter.

What is the definition of density?

Density is a property of matter representing the mass per unit volume. :)

How is viscosity and density related?

Viscosity is the thickness or thiness of a fluid, Density is the space between particles.

When a fluid is heated, it becomes less viscous(thinner) and the particles move far apart so it is less dense. Temprature affects density and viscosity.

Something that is dense doesn't have to be viscous and vice versa.

EX: Salt water is dense but not viscous.

Honey is very viscous but not very dense

How is density related to floating?

You must compare the densities of the object and whatever substance you are putting it in. If the density of an object is greater than the substance it is in, then the object will not float on the surface

What is the density of water?

The density of a material is defined as its mass per unit volume.

The density of liquid water is normally given as 1000 kg/m3 or 1 g/cm3 as a very accurate estimate, but often ranges slightly below this value, depending on temperature.

Unlike other agents that tend to freezing point, water tends to expand as at freezes; it therefore becomes less dense. Thus, the density of solid water is normally given as just over 91% of this; a common given value is 9.17 g/cm, or 9170 kg/m3.

Density is determined by?

Density is determined by the mass of a substance divided by its volume. It is a measure of how tightly packed the particles are within a material. Materials with high density have more particles in a given volume compared to materials with low density.

Which has a greater density a metal or a liquid?

The question is deeply flawed.

Many metals are denser than many liquids, but many liquids are denser than some metals (and then, of course, there's mercury, which is both a metal and a liquid at room temperature).

If all you know about two substances is that one is a liquid and one is a metal and you're forced to bet your life on which is denser ... your odds are probably SLIGHTLY better betting on the metal.

What does density mean?

The "density" of something is a measure of how much it weighs (technically, its mass) per amount of space it takes up (its volume). The formula for density is

Density = mass/volume.

So something that is very heavy but doesn't take up much space (like lead) is considered to have a high density, but something that is light and takes up a lot of space (like feathers) has a low density. So the word "dense" usually refers to things that have a high density.

It is also commonly used colloquially to refer to somebody who is maybe a bit slow to understand things (a reference to their skull being dense, thus not allowing much in or out of their brains).

What is the density of gasoline?

The density of gasoline can vary depending on the type and temperature, but it is typically around 0.74-0.85 grams per cubic centimeter.

What is the density of aluminum?

2800 kg/m3 (2.8 g/cm3 )(0.098 lb/in3)

--- alloys range anywhere from 0.097 lb/in3 (2.7 g/cm3) to 0.103 lb/in3 (2.9 g/cm3)

What is chip density?

Chip density refers to the number of transistors that can be packed onto a piece of silicon in a computer chip. Higher chip density allows for more powerful and efficient processing capabilities in electronic devices.

Which non-metal has the highest density?

The non-metal with the highest density is iodine, with a density of 4.92 grams per cm**3.

Why is density important?

Density is important because it helps determine how much matter is packed into a given space. It is a physical property that can help identify substances or materials, as different substances have different densities. Density also plays a key role in buoyancy and can be used to predict how objects will interact in fluids.

What is the density of brass?

The density of brass can vary from 8300 to 8700 kg/m3.

What is the weight of air per cubic yard at sea level?

The weight of air at sea level is approximately 0.075 pounds per cubic foot. One cubic yard is equal to 27 cubic feet, so the weight of air per cubic yard at sea level would be approximately 2.025 pounds.

Formula of density?

Density is defined as mass per unit volume and is typically represented by the formula ρ = m/V, where ρ is the density, m is the mass of the object, and V is the volume occupied by the object.

Density of an egg?

Density=Mass/Volume. Your gonna have to figure that out yourself

Density of rubber?

The density of rubber can vary depending on the type of rubber. Generally, the density of natural rubber is around 0.92 g/cm3 to 0.96 g/cm3, while synthetic rubbers like neoprene have densities ranging from 1.1 g/cm3 to 1.6 g/cm3.

Symbol for density?

In lower classes viz sixth standard, the first letter of the word "density" ie 'd' is used.

But later in higher studies instead 'd', 'rho' the greek letter is used as the symbol for density.

What is the density of sand?

Density of sand can vary depending on the grain size and moisture content and how tightly it is compacted

If you dont need very accurate densities the following should help

Sand, wet 1922 Sand, wet, packed 2082 Sand, dry 1602 Sand, loose 1442 Sand, rammed 1682 Sand, water filled 1922 Sand with Gravel, dry 1650 Sand with Gravel, wet 2020
density of sand will vary depending upon the condition.that is for wet,dry,gravel..
