Density of ice water?
449704
Water is water. The density of ice water is 1000 kg/m^3. It isn't floating is it? Then it must not be below 1000.

Take a glass full of water. Put an ice cube on the surface. It will float on it.  Wipe out the spilled water. \n\nAfter certain time when the ice cube is completely melted, you can observe that not even a single drop of water spilled out and the water surface is still up to the brim.\n\nThis shows that the volume water displaced by the ice cube when it floated is equal to the volume water when it is completely melted.\n\nSince it was floating, the weight of ice cube is also equal to the weight of the diplaced volume of liquid.\n\nThis again shows that the density  of ice is lesser than water.

This answer will depend on the density of the water that is used.  According to Wikipedia the density of Water is \n1000 kg/m^3.  The equation for density is as follows:\n\nDensity=Mass/Volume\n\nMultiply both sides by volume gives us the following equation\nMass=Density*Volume.\n\nGiven: \nVolume=1 cubic foot\n\nDensity of Water=1000 kg/m^3 \nYou most likely want how many lbs of water you need; thus we need to convert the Density of water from kg/m^3 to \nlbs/ft^3\n\nThus using an online conversion:\n1 kilogram/cubic meter = 0.062 427 962 pound/cubic foot\n1000kg/m^3= 62.43 lb/ft^3\n\nThus finally\nMass=Density*Volume\nMass=62.43 * 1\nMass=62.43 lbs approximate!\n\nNow since your designing it you want to design over 25%\nso therefore design for 78.04 lbs.  Worry about the pressure on the sides more when designing this system.

I don't have to resources in front of me to really compute the answer, but this should give you the answer.\n\n1) you know the freezing point of water is zero degrees Celsius.\n\n2) find the moles of NiSO per kg of water (molality)\n\n3) use the following dimensional analysis (with 'X' being the previous answer): (X mol./kg)*(1.86 degree decrease/1 mole NiSO added) = Y\n\n4)Since there is 100% dissociation, the answer should be  0 - 2*Y (vant Hoff factor).\n\nThis means your answer will be a negative (below zero) number with Celcius as the temperature units

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

Yes, you can get very many experiments on density. Depends on what you want to do with density. If you want to compare the densities of to different solids in relation to a particular liquid (e.g water) You just measure their dimensions and divide their  mass by their volume to get their density (If you don't know already) . Then you find their Relative density using the equation.

Density = mass / Volume\n\nYou are given the mass of the cyllinder (m = 4 kg).\nYou are given the dimentions of of the cyllinder which you can then use the find the volume.\n\nThe volume of a cyllinder = (pi*r^2)*h\nwhere pi is the constant pi (the ratio of the circumfrance of a circle to its diameter, ~3.1415), r is the radius, and h is the height.\nUsing this formula, I calculate the volume of the cyllinder to be about 9425 cm^3.\n\nD = m / v\nD = 4000 g / 9425 cm^3\nD = 4.24 E-1 g/cm^3 or 424 kg/m^3\nThis is a low density by comparison to many other things, for example, water has a density of about 1 g/cm^3.\n\nNext Time, do your own home work.

Ice is less compact or less dense than liquid water.

Can't give you a definite answer but as the primary ingredient will be water it will have a density very similar to that of water which is 1.000.

The density can be assumed to be 1.0 g/ml.  \n\nSo you have 25 ml x 1.0 g/ml = 25 g H2O\n\nThe molar mass of water is 18 g/mol, so you have:\n\n25 g H2O/18 g H2O/mol H2O = 1.4 mol H2O

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.

You shouldn't be talking about mass but about volume. Whatever happens to the ice--if it melts, if it boils, there is NO change in mass. Only volume.\n\nLet the total volume of earth's ice-caps be x; let y percent of this ice be above water.\n\nFor there to be no change in the sea level if all the ice melts completely, the ice above water must make up for the loss in volume of ice underwater--which becomes a smaller volume of water than it was as ice.\n\n ice above water = x [times] (y/100) = (xy)/100\n\n ice below water = x - (xy/100) = (100x-xy) / 100\n\nwhen melted; ice that was above water has the volume \n= 0.92 (xy/100)\n\nwhen melted; ice that was below water = 0.92 ( 100x-xy)/100\n\nhow much less space does melted ice underwater take up than frozen ice \n= 0.08 (100x-xy)/100\n\nthus 0.08(100x-xy)/100 = 0.92 (xy/100)\n        8x-0.08xy = 0.92 xy\n        8x = xy \n          y = 8\n\n...that's what I got. Do you have the answer?

Density plays an important role in the working of the planet.  Less dense things rise above more dense things.  Also, density changes with state (solid, liquid, gas).  Consider water, it is the only substance where the solid form is less dense than the liquid form.  Because of this, ice floats.  Imagine if ice didn't float, but sank.  When the tops of lakes froze in the winter, the ice would sink down to even colder areas (and not melt), then the next layer would fall on top of that one.  Eventually the whole lake would be a block of ice.  There might even be similar events with entire oceans or at least in the polar regions.   Density also affects heat transfer.  The more dense something is, the more molecules there are in contact with each other.  What heats up faster, air or cement?  Cement, because the molecules constantly collide with each other whereas in air, there is so much empty space that they often miss each other.  Therefore there are fewer collisions and less heat is transferred.  Hope this helps get your mind jogging.

Not quite right.  It is most dense at 4 degrees C.  If it didn't, the water would freeze from the bottom up.  As it approaches 0 degrees, it becomes less dense and rises above the more dense warmer water and freezes on the surface and goes down.  Otherwise, fish would be on top of the ice and die after it froze.

water has density 1gm/ml. what ever is the volume in ml for water same is the mass in gms because density = mass/volume\n\n\ni hope it will help you out

Density of ice is less than that of water.
