>>>>>at 4 degrees above its freezing point, water sinks.\n\nThis is true.\n\n>>>>any lower, and it begins to freeze, forms crystals, and floats.\n\nThis is not true. Water begins to freeze at 0oC, not at 3.9oC or even 1oC.\n\n>>>>any warmer, and the molucular action makes it less >>>>dense.\n\nThis is not true. Water becomes less dense at warmer temperatures due to kinetic motion impeding the formation of hydrogen BETWEEN molecules.

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.

The temperature of the ocean at depth, anything more than several hundred feet, is 3.98 degrees C.  This is the temperature at which water is densest.\n\nIf any geothermal heat from the sea floor warms the very deepest water, it becomes less dense and rises.  And any shallower water warmed by the sun is too buoyant to descend towards deeper water.  3.98 degrees C is it, all the way to the bottom.

since water is very dense, meaning very hard, yes sure. but it has to be coming at you at a great force or vise versa.(you coming at it really fast)

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.

1. The bouyant force of the water on the object is the difference in the reading, i.e. BF=(.0554-.0370)g\n                                   =0.0184gN\n\nBased on Archimedes' Principle, BF =Volume*Density of water displaced.\n \n0.018g=Volume*1000g\nVolume=.018/1000\n            =1.8*10^-5m3\n\n2. Density of Object=Mass/Volume\n                                =.0554/1.8*10^-5\n                                =3078kg/m3

It would be because of the density of the matter..

at 4degree c water has highest density but if we increase or decrease the temperature water density start decreasing . when we decrease temperature of water water molecules start  attaching with eachother by inter moleculer hydrogen bonds  one molecule of water associates 4 other molecules by this bond ,forming a big  molecule  but all the molecules of water in  this  big molecule is not well packed and a lot of space is left in side the big molecule we call it cavity and this cavity increase the volume but not the mass . so density decrease means volume increases,\n  but if we change the ice into water then this intermolecular hb breaks and  free water molecules start filling this cavity and hence density increases upto 4degree c, but if we further raise temperature the thermal expansion of the water happens and it causes density decreasing ie volume increement

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!!

The density of pure water is 1.0\nThe density of ice is .92 (ice expands when it freezes, so the density drops)\nThe density of sea water is 1.025 (sea water is denser then pure water because it is salty).\n\nAn ice cube floating is a glass of water is 92% submerged (compare their densities.)\n\nAn ice berg floating in sea water is 90% submerged (.92/1.025)

125% the density of water.

I'm not sure. But the volume of a sphere is (4/3)(pi)(r)^(3). \n2) You know that the diameter is double the radius. So your radius is 1.\n3) Then, your volume is (4/3)(pi). \n4)Density=(mass/Volume)\n5)Density of water is 1.00 mL=1.00g/m^3\n6)MASS=(Density)(Volume)=((1.0g/m^3)(4/3)pi). Note that cubic meters cancel. The mass is (4/3)pi grams.\n\nHope I helped.

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

Water reaches a density maxima at 4C.

floating shows that an object is less dense than water.  Think cooking oil spilled into a kitchen sink.  Does it float on top, or does it sink?\n\nLet d=density:\nd(water)=1.00\nd(oil) < 1.00, therefore it will float\n\nBut also, a chunk of iron (I believe) has a density of around 5.00 (of some unit, it's been two years since I've dealt with density questions on a regular basis.  Someone want to patch my answer for me?).  Since it is greater than that of water, it will drop like a rock to the bottom.\n\nd(lead,iron, etc.) > 1.00, therefore it will sink.
