Does the size of aluminum foil affect its density?

No, size does not effect density.\n\nDensity is equal to the mass divided by the volume,\nD = m / v\nFor any uniform material, the density of will be the same no matter how much you have of it.

The mass of a nickel is a 5.02 g. Its density is 8.90 g/mL!\n\nI hope I'm first!

I think this is an interesting question.  Surprisingly, I think the answer is yes for some properties.  I don't have data in front of me (my books are at the office), but I'll bet that if you compare densities of homologous compounds in a group, you'd find that the density increases along with the density of the main constituent atoms.  I'll also bet that there are spectroscopic properties that are retained -- those relating to the inner shells.  In addition, there are tests used by mineralogists to detect the presence of common constituent metals in different minerals; a common example is the sodium "D" emission that causes a yellow flame in a fire when sodium is present regardless of the counterion.  In inorganic chemistry I seem to remember endless graphs of periodic properties that we used as a mnemonic device, but that was too many years ago to remember them.\n\nIf I wanted to look into it on the internet, I'd do a search on "periodic properties of the elements."  Also, geochemists are wonderful for collecting data and putting together tables of such things, and undergraduate inorganic textbooks may be helpful for finding some as well.

Each time you fold it, it doubles in thickness and halves it surface area.\n\n0.1mm x 2 ^ 40 = 109,951.1627776 km\n\n(68,320 miles)\n\nThat means that the piece of paper would be so thick that it would reach to the Ionosphere (well past the ozone layer!)\n\nAlthough the thickness of the paper would be huge, the surface would be tiny. Say you had a large sheet of paper\n1m x 1m (3'4" x 3'4")\n\n1(m^2) / 2 ^ 40 = (m^2) = 0.90949 (μm)^2\n\n(0.0000000014097 square inch)\n\nSo basically your talking about a large piece of paper that now has such a small surface as to become invisible and so thick that it may get hit by international aircraft!\n\nThat is ridiculous and impossible! Incidentally, no paper can be folded more than 8 times.

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!!

I Dont know what sumink is, but if you want to increase the density of any object while keeping its mass constant, its volume has to become smaller (more compact, more dense), hense its radius would decrease as well.

The mean van der Waals diameter of water has been reported as identical with that of isoelectronic neon (2.82 Å) [112]. Molecular model values and intermediate peak radial distribution data indicates however that it is somewhat greater (~3.2Å). The molecule is clearly not spherical, however, with about a ±5% variation in van der Waals diameter dependent on the axis chosen; approximately tetrahedrally placed slight indentations being apparent opposite the (putative) electron pairs.

If there are bubbles of air then you will have less liquid than you are intending to have. Assuming you are calculating density via measurementof mass then the mass you get will be less than it should be for that volume of that liquid. As a result the calculated density will work out lower than it should do.

Lacking more detail - my suspicion is that the release of H2 will cause the amount of aluminium to be to high...\n\n-dh

Density - 1.151 \nNot easy to find

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.

You need to know the density.

i agree that it's probably lead.  lead is very dense, so your things should feel very heavy for their size.  you can verify this by a couple methods:\n\n1.  get an accurate scale and measure the weight of a piece.  then get a graduated cylinder from your school and fill it partway with water.  dunk the same piece of the metal into the water and see how much the volume changes.  divide the weight by the volume to get the density.  compare this to the density of lead which is 11340 kg/m^3 or 11.34 grams/mL.\n\n2.  if you have a voltmeter, do the following:\n - get a tub of water and dissolve some salt in it\n - cut out a strip of aluminum foil and immerse one end in the water\n - take your mystery metal and immerse one end in the water\n - make sure the two metals aren't touching\n - connect one probe of the voltmeter to the aluminum, and the other probe to the metal.\n - aluminum has an electrode potential of 0.13 V and aluminum has an electrode potential of 1.66 V, so if lead is the metal then the voltmeter should read 1.66 - 0.13 = 1.53 V.\n\nsounds like you are going to have some fun!\n\nalso, lead is toxic so wear gloves and wash your hands after you handle it.

I am going to assume that you mean less dense.  The answer heat was correct. There are many chemicals that can be dissolved in water to make it less dense. \n\nBut, if your question really is to make a set amount of water lighter then the answer is no. Anything that you add to it would either have no measurable effect to its weight or would make it heavier even if less dense.  \n\nHowever because you are talking weight and not mass there is a possibility. If you put a jar of water on an oil proof scale inside of a larger jar and added oil to the larger jar the jar of water would weight less. So I guess there are things you can do to manipulate the weight and the density, but not the mass. \n\nExcept if you added enough pressure you could make the hydrogen and eventually even the oxygen to go through a fusion reaction and that would convert some of the mass into energy and therefore make it both weigh less under equal gravitational conditions and be less massive.\n\nI guess with such a loosely worded question there are lots of possibilities. Of course you could even go the route of adding a luminescent chemical to lighten it up. Add a colloidal oil that turns it white.\n\nYou could add a group I metal to it which would make it lighter by many different definitions of lighter and brighter, but I would not suggest doing this.

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.

It would decrease insulation.  Fiberglass insulation is engineered with air pockets for optimum heat retention.\n\nIf it WAS better to pack it in, manufacturers would sell a higher density product and charge more.

The question is either incomlete or it doesn´t make sense. Are you looking for the atomic mass, density or somethig else.\nAs it is, the best answer to your question would be: "depends on how much aluminum".
