Density is simply mass per unit volume.  The density of a substance is directly related to the atomic weight of the element composing it, ie., elements with higher atomic weight can be thought of as being “heavier”.   Another way of stating this is that equal volumes of two different substances have different densities because each different substance has a different mass (ie, atomic weight) and crystal structure.  There are many types of units which can be used to measure the mass of a substance (pounds, grams, etc.), just as there are many types of units which can be used to measure volume (cubic feet, cubic centimeters, etc.).  The standard units of measure for density are grams/cubic centimeter.  \n\nDifferent minerals or rocks can vary greatly in density, depending on their chemical make up.  Density is such a characteristic property of a substance that it may be used to identify the substance.  Geologists have found it useful to develop a system of comparing densities of different minerals or rocks by calculating a numerical value without units known as “specific gravity”.  The specific gravity is the weight of a substance compared to an equal volume of water.  Water is chosen as the substance for comparison because by definition it has a density of 1 gram per cubic centimeter (at 4o C), and also because it is such a common substance.  For example, compare the density of a rock like granite to water:  a cubic foot of water weighs 62.5 pounds and a cubic foot of granite weighs 168 pounds.  The specific gravity of granite is:   168 / 62.5  =  2.7.   Granite is 2.7 times heavier than water.

hey man, dont worry ill help. first of all our given:\nh=280m\nsg=1.03\ngc=9.7m/s^2\n\nreq'd Pressure(absolute)\n----------------------------------------------\nsol'n:\nfor DENSITY of subs:\nformula\nSpecific Gravity=density of subs/density of water\ndensity of subs=1.03 x 1000(density for water)\ndensity of subs=1030 kg/m^3\n\nFOR PRESSURE GAGE:\nP(gage)=Vh\nP(gage)=density x gravitational constant x height\nP(gage)=1030 x 9.7 x 280\nP(gage)=2,797,480 Pa\n\nFOR PRESSURE ABSOLUTE:\nP(abs)=P(gage) - P(atm)\n\nwhy minus? bec. the submarine is pressurized, meaning its vacuumed\n\nP(abs)=2,797,480 Pa - 1atm(101.325x10^3 Pa)\nP(abs)=2,696,155 Pa\n\nconvert Pa to Kpa\n=2,696,480 /1000\n=2,696.155 Kpa\n\nconvert to bar\n=2696.155kPa x (1.01325 bar / 101.325 kPa)\n=26.96155 bar\n\ndont mind the others, they dont even know how to answer this simple question. They just want to earn points!

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

Convert all this to MKS units and find the cross-section of that wire.\n\nE (stainless-steel) is given to be 18 x 10^10 N/m^2.\nCross-section is from pi(r^2).  This must be in m^2, not mm^2.\n3.14159(0.125*10^-3 m)^2 = 4.909 x 10^-8 m^2 cross-section.\n\nYoung's modulus (E) is given as,\n\nE = (delta F / cross-section) / (delta length / original length)\n\nDelta F is the tension in the wire, thats the first part of solving this problem.  So rearrange the equation for delta F, renaming delta F as "tension" and substitute the value given in place of E:\n\nTension = (18 x 10^10 N/m^2) * (8 x 10^-5 m / 0.028 m) * (4.909 x 10^-8 m^2)\n\nTension in the wire is therefore 25 N.\n\nThe magnitude of force on the tooth is 25 sin 30 deg or 12.5 N\n\nWarning!:  While the reasoning is sound, double-check all of my math.  Also, note that I rounded the intermediate answer 25 N.

You would need to know its coefficient of thermal expansion.  You then apply it to the volume and use a ratio to find the new density.  If the coefficient is linear, a, then V_f = V_i*T*(1 + a)^3, where the subscripts f and i are for final and initial, respectively, and T is the change in temperature.  If the coefficient is cubic, g, then V_f = V_i*T*(1+g).  Either way, the new density is p_f = p_i*(V_i / V_f).

The rather loose grammar in use on Yahooanswers makes your question ambiguous.  Do you want to know what of what value stiff steel is? If so, the answer is obvious; the uses of steel in construction, consumer products, automobiles, etc. are myriad.\n\nIf you mean instead, what numerical value of "stiffness" does steel posses, there are several possible answers.  One would be the shear modulus of steel, which is a measure of how much a substance deforms when a shearing force is applied.  It is define as S= Shear stress/shear strain= F/A)/ (DEL X/h) where F is the force applied parallel to an object's fixed end, A is the area over which the force is applied, DEL x is the distance the object deforms, and h is the height of the object.  For steel, this is 8.4 x 10^10 Pascals.  Compare this to 2.5 x 10^10 Pascals for aluminum, and 14 x 10^10 Pa for tungsten.

Your density will be similar to whatever material makes up the planet.  For instance, Mars is mostly rock, with some iron ore.  I'd guess the density is on the order of 2.5 g/cm3.  Jupiter is made up of mostly dense gases.  I'd guess given the temp, that the density is slightly higher than that of water, like 1.3 g/cm3.\n\nVolume on the other hand.......are you kidding?  You seriously want it in cm3????  You'll run out of room on your paper writing zeros.

Saturn has a density less than water.  It's density is 0.6873 g/cm^3.  Water has a density of 1g/cm^3.

we know that mass = volume * density\nin the first case, mass = 278.1g\nvolume of the cube = 3*3*3 = 27 cm^3\ntherefore density = mass/ volume\n density of steel = 278.1/27 = 10.3\nThrefore the mass of 1 cm^3 of steel= volume * density\n                                    = 1 * 10.3\n                                    = 10.3 g\n\nNote: denstiy of any material is always a constant- it is an intrinsic property of the material. It is important to get these concepts right when you study them so that you can have a good foundation for higher studies. Please promise me that once you understand how to do this problem, you will try it on your own. Thanks. goodluck

The first part is correct.  If the numbers in the second part are correct, it is true only for an ideal gas.  Other materials have various densities in their liquid and solid states.

less dense... it is common sense the density of substances go from solid liquid to gas (most dense to least) neon is a gas thus it would be less dense than water which is a liquid

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.
