What is the realaitionship between bouyancy and density?

Buoyancy is a force.  Density is the ratio of an objects mass to volume (D=m/v).\n\nThe buoyancy force exerted on an object is dependent on the amount of (for lack of a better work) "stuff" it displaces.\nFor example, a ship floating in the water floats because the weight of the water it displaces is greater than its own weight.  Likewise, a balloon filled with Helium will float because the weight of the air it displaces it more than its own weight.

Go back to basics...\n\nDensity = mass / volume\n\nSo for compressible fluids if the volume goes down the density goes up...if the volume goes up the density goes down.  In general then we can say that density of a compressible fluid is inversely proportional to volume.

Density doesn't have properties. Density IS a property of all matter. All matter has density. Density measures the amount of matter in a given volume. In other words, density measures the amount of 'stuff' packed into a given shape. The formula for density is density = mass divided by volume.

Hello,\nDensity is mass per unit volume.  The density of fresh water is one gram of mass per cubic centimeter.  Since, the ocean water has salt in it, there is more mass per cubic centimeter of salt water.  If you think about a glass full of fresh water and a glass full of salt water, you can easily see that the glass full of salt water has a lot more material(mass) per cubic centimeter than the fresh water does.  So the glass full of salt water (or the ocean)is more dense than the glass full of fresh water.\nAnd that affects a boat by making it float higher.  When an object is placed in water, it displaces as much mass of water as is contained in the object.  Again you can think of a glass of water.  If the glass is filled to the top and you place an object of mass M-grams in the glass, then the amount of water that spills out is M-grams.  The object displaces the mass of the water by sinking into the glass.  Once it has displaced M-grams of mass, it can't displace any more, therefore it will stop sinking as soon as it displaces M-grams.  So since each cubic centimeter of salt water is made up of more mass than fresh water, the object will displace less cubic centimeters of salt water than of fresh water, so it will float higher.

Measurements (In distance I'm assuming) would give you volume.\n\nMass / Volume = Density\n\nIf you have volume & density, you can rewrite the equation:\n\nMass = Volume * Density

You must show not tell. Take a bowl filled to the top with water and put it on a plate to catch overflow. The put objects in the water and compare the overflow for sinking and floating objects of the same size. If you have a scale weigh the objects and the water if not just hold them and judge weight. Then explain density.

Density is mass per volume... so divide the 2 kg by 240 cm3 and you will get your answer.

Here you go ...\n\na)  The idea of buoyancy was summed up by Archimedes, a Greek mathematician, in what is known as Archimedes Principle: Any object, wholly or partly immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object. \n\nb)  DENSITY is a physical property of matter, as each element and compound has a unique density associated with it. Density defined in a qualitative manner as the measure of the relative "heaviness" of objects with a constant volume.\n\nFor example: A rock is obviously more dense than a crumpled piece of paper of the same size. \nA styrofoam cup is less dense than a ceramic cup.\n\nDensity may also refer to how closely "packed" or "crowded" the material appears to be - again refer to the styrofoam vs. ceramic cup. \n\nc)  Low pressure areas have less atmospheric mass above their location, whereas high pressure areas have more atmospheric mass above their location. Similarly, as elevation increases there is less overlying atmospheric mass, so that pressure decreases with increasing elevation.  As elevation increases, the number of molecules decreases and the weight of air therefore is less, meaning a decrease in air pressure. In fact, while the atmosphere extends more than 15 miles (24 km).\n\nI hope this helps.

Density= Mass/Volume.  When water freezes, its volume increases. This is why a frozen bottle of water expands to the point of bursting. By the formula, if volume increases and Mass stays the same, then the value of density decreases.  Thus, this is why ice floats and is less dense than water.  When the ice melts, the reverse happens in that its volume decreases and again by the formula, density will increase.   Tahdaaaa!!

Intensive properties do not depend on the sample size whereas extensive properties do.  An intensive property would be the melting temperature which obviously doesn't depend on sample whereas an extensive property would be something like volume, which obviously depends on how much stuff is present.

you cant you have to have mass and volume to find density

density is mass divided by volume - so if you know the volume and the density, then you multiply them to get the mass  (which is synonomous with weight)

Volume = 1/48 * 1*1 = 1/48 cu ft\ndensity = 480 pounds per cu ft\n\nmass = density*volume = 480* 1/48 lb = 10 lb

You should use density to check that out.\nDensity=Weight/Volume

Mass is the ammount of space a thing takes up. Density is how hard/solid an object is. Volume is the inside of something (similar to area.) Sorry if my answers aren't enitelry correct!

Density is mass per volume.   \nDisregard the weight; it's irrelevant.\nUse volume = lenght * width * height (or depth).
