How is density used in everyday life?

Density = Mass / Volume\nIf you know any 2 of the above quantities, you can find the other.

the most common formulas involving mass and density are:\n\nD=M/V     (D is density, M is mass, and V is volume.   \n                the "/" sign means division)\n\nyou can use this equation to find other equations.\n\nVD=M        (Volume times Density equals Mass)\n\nM/D=V        (Mass divided by Density equals Volume)\n\n\nas far as definitions for mass and density, mass is how much matter is contained in an object and density is the ratio of the amount of matter to the amount of space it takes up.

density has an equation density=mass/volume\nClay in a ball has the same mass and volume as rolled into a ball (considering of course no clay comes off on the table). So the density would be calculated the same,no matter the shape.

Need to be more specific in your question.  There are many different types of salts, each with their own densities.

Density=Mass/volume, Therefore heating a gas increases its volume. This change has to be compromised by either mass or density. Mass cannot vary as it's a constant, so the density has to give way. Hence the change in density. When volume increases, density decreases as they are inversely proportional.

1. You could look up lists of known densities for a match.\n\n2. If not found, the density can give you a clue concerning the nature (metallic, organic, etc) or category.

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)

Because it's dense...

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

To determine density you also have to know the temperature.  The colder a substance gets, the more dense it becomes (ie. the particles come closer together).  Water is the one odd ball, it becomes most dense at 4 degree C instead of below freezing like most substances.

Density = mass / volume.\n\nJust divide the given mass by the given density, the result you get is the volume.\nSo\nvolume = mass/density.

Volume is defined as the amount of space occupied by an object. Density is defined as the amount of mass per unit volume.In other words If there are two objects of volume one litre, And the mass of the first is greater, then the density is also greater.\nDensity=mass/volume. Hope that cleared your concept.

density = mass/volume.\n it changes wt respect to temp.\n as temp increases,volume increases and so density decreases. however there may b some exceptions.\n  as an example, if v heat water to high temp but less than it's boiling point, it's volume increases.\n  so, v can say that the density is less than the previous condition.

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!

Hot air is less dense than cold air, assuming that volume is held constant, because the molecules in the heated air move more and faster than in cold air.  Think about a room filled with people.  If the people move around quickly (as molecules in heated air), then the people will spread out more and make more room between eachother (which would be lower density).  Since the hot air is less dense, and more dense objects are "more affected" by gravity, then the warm air is "lighter".

The density of the fluid and the density of the object.

make a little "boat" that you can add weights to and float it in the different liquids.  Gradually add weight to the boat in each liquid to see how much it can hold before it sinks.  The more weight the boat can hold, the greater the density of the liquid!\n\nThis is basically a poor-man's hydrometer.
