The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume. The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume:
where ρ is the density, m is the mass, and V is the volume. In some cases (for instance, in the United States oil and gas industry), density is loosely defined as its weight per unit volume, although this is scientifically inaccurate – this quantity is more specifically called specific weight.
For a pure substance the density has the same numerical value as its mass concentration. Different materials usually have different densities, and density may be relevant to buoyancy, purity and packaging. Osmium and iridium are the densest known elements at standard conditions for temperature and pressure but certain chemical compounds may be denser.
To simplify comparisons of density across different systems of units, it is sometimes replaced by the dimensionless quantity "relative density" or "specific gravity", i.e. the ratio of the density of the material to that of a standard material, usually water. Thus a relative density less than one means that the substance floats in water.
Steve Spangler (born December 8, 1966) is a television personality, author and science teacher. Spangler founded Steve Spangler Science and its wholesale division, Be Amazing Toys. He serves as CEO of Steve Spangler Science and the creative director of Be Amazing Toys. Both companies develop science education teaching tools and toys. Spangler posted the first Diet Coke and Mentos video on YouTube in September 2005 and his 2002 televised demonstration of the eruption went viral launching a chain of several other Diet Coke and Mentos experiment viral videos. He earned two Heartland Emmy Awards and a total of five Emmy nominations. Spangler holds a Guinness World Record for the largest physics lesson and is an inductee of the National Speakers Association Speaker Hall of Fame.
Spangler's career began as a science teacher in the Cherry Creek School District in Colorado. As part of a science outreach program, Spangler created a traveling science show targeted to elementary and middle school students in an effort to increase interest in science. In 1991, Spangler began traveling throughout Colorado and the surrounding states to present school assembly programs and teacher training workshops focused on using more inquiry-based science activities in the classroom.

Just like all matter water has physical properties that can be measured and calculated. To find the mass of water you will need a beaker and a scale. First find the mass of the empty beaker. Next, fill up the beaker to your desired amount. Then use the scale to find the mass of the filled beaker. To find the mass of just the water, subtract the mass of the empty beaker from the full beaker. Our sample is 100 grams. The volume of water can be measured using a graduated cylinder. Our sample is 100ml. Density is calculated by dividing the mass by the volume. Plug in our measured mass at 100 grams and divide that by our measured volume of 100 ml. Water's density is 1 g/ml. Objects with a density greater than 1g/ml will sink when placed in water. Objects with a density less than one wil...
Topic: Density Why do firemen crawl in smoke filled rooms? Hey!! Remember, the upper part of the room will be filled with smoke. So, crawl while you are going inside!! Why don't you listen?? Look!! You are not able to breathe properly as you have inhaled a lot of smoke!! This happened because you did not care about the density of air. Don't worry!! I will explain. Density is the measure of mass present per unit volume. Lesser the density, lighter will be the object and greater the density, heavier will be the object. So in this case, what is lighter, the air or the smoke?? Yes, you are absolutely correct!! Smoke is lighter than air. As it is lighter, it rises up in the room and occupies the space at the top. Hey!! Where are you going?? It is not over yet. The air being heavier than ...
To see all my Chemistry videos, check out http://socratic.org/chemistry We'll practice solving density example problems. We'll look at how to use the density number like a conversion factor, to solve for mass or volume. Watch this video after the density introduction or before the more complicated video on density exercises that has unit conversion.
Which is heavier, a pound of bricks or a pound of feathers? In this video you find out the answer to this age old question. You will also learn how to find the density of objects give the mass and volume of an object.
Topic - Density Why does oil float on water? Hey! Did you realize that a large log of wood floated on water but a comparatively smaller piece of rock sank? How is this even possible? This is possible because of density. It is the measure of the mass of an object per unit volume. In the first case, the log of wood floats on water because it has less density than water. This means that the amount of mass present in unit volume of wood is less than the amount of mass present in unit volume of water. However, in the second case, the piece of rock sinks because it has more density than water. This means that the amount of mass present in unit volume of rock is more than the amount of mass present in unit volume of water. Do you know why the helium filled balloon is rising up in the air? Thi...

Consider that a black hole has the same density as the earth if it was squashed down to the size of a golf ball. It's a difficult fact to comprehend and for a long time black holes formed the stuff of science fiction but now they are a scientific fact.
Simple density science experiment that you can try at home to see how liquids and objects with different densities behave. Using three fluids (syrup, water and oil) we can see they clearly have different densities, and form clear layers. By dropping items with different densities into the glass, we can see which fluids are denser than them.

Body centered cubic (BCC) and face centered cubic (FCC) unit cells are introduced using models. These two unit cells are then broken down into how many atoms are present for each, which atoms are in contact with one another and how to relate the length of the unit cell with the radius of the atoms composing them. A density problem is solved where the density of aluminum packed in a FCC arrangement is used to find the radius of an aluminum atom. The atoms at the corner of a unit cell have only 1/8th count towards each unit cell, the atoms on a side count 1/4th, the atoms on a face count 1/2 and any atoms completely internal to the unit cell are not shared and thus count the full atom towards the unit cell.

Learning why Gravity has to be dismissed is crucial. Answering some of the religious science "faith" counter points in the comments will hopefully help SOME who are not blinded by their own cognitive dissonance to see how gravity fails to answer all that it must. Density is something that gravity can not account for in that model. It simply can't and doesn't. It fails to explain what we experience. The two videos (this is #2 and follows "Blowing Gravity (Literally) out of the Water" are not an attempt to discuss attraction of objects to the earth. They are to explain density and how density alone eliminates the theory of gravity from being considered valid. To hold onto a theory when it does not and can not explain what we experience on earth is foolish. Only a blind faith would hold onto...

There is a God and I bow and you will hate me for it!
Duty to humble my soul to a speck of dust and you'll hate me for it!

I will love God of "Zion" with all my heart and you will hate me for it!
Intentions will be so helples and you will hate me for it!
I will love through resurrecting eyes and you will hate me for it!
Self exultation is the opiate of the masses.
