If you could make a fullerene tubule long enough, to what height would water be drawn by capillary action?

Not enough info-that would completely depend on the diameter of the tube, and just saying "fullerene" leaves diameter an open question.

air would rush into the empty tube and filll the vaccum and some may escape in to space but not very much.\n\nTake a straw and plug the top insert it into a glass of water - remove your finger. if your straw wa almost all the way under you will shoot a little water in the air but the cupp will not empty - physical principles are the same

or_try_this is correct.  It is dense, and a 30-inch column of mercury fits in a laboratory better than a 34-foot column of water.  It is stable and doesn't evaporate at room temperature.  Its thermal expansion can be compensated for, but it's usually small compared to the pressure differences it's measuring.  It looks scientific, too.

one is a long tube of that is 10 - 100 nm around but can be very long (5 mm or so)   while a nano particle is basicly a sphere that is 10-100 nm in radius\n\n(i belive that carbon nano tubes can be classifide as nano wires)

Adding water to sodium metallic particles - watch them sizzle but be careful!!!

For C, that would normally be true.\n\nFor D, the answer is 1.2X10^24 atoms.\n\nFor E, helium atoms escaped through effusion.

Check the Michaelis-Menten equation.It's too long to write it all down for you ;)

The problem is the transport of water to the top. Depending on the species, the power of the capillaries is limited (perhaps the wrong word, I'm not so common with biology in English).

Dialysis tubing can come in various pore sizes that allow selective passage of materials. This is like a cell membrane that is also selective, but not really in terms of the size of the material. It has to do with the polarity (cell membrane is bipolar-has polar head with long, non-polar tail, but two chains of this with non-polar ends facing inward on the membrane and polar heads facing the outside of the membrane). Polar molecules (such as Na+ or K+) need to go through membrane-bound protein channels or receptors.

Yes.\n\nThere are two states for liquid helium. In the second state it has such a low surface tension that it does flow uphill.\n\nIf you put water in a glass and look at the very edge of the surface you will see it curve from flat, upward to the glass. The water molecules are being attracted to the glass, but are pulled back by attraction to other water molecules and gravity. With helium, this happens but the attraction to spead out is greater....

You need to give more information about the shape to get a definitive answer.  If the cell were cubical, then the volume increases 1000 times if all three sides increase 10 times in length.

I got this from my physics prof.  Take a full glass of water, preferably a wine glass, and and some food colouring for the water.  Take a clear piece of acetate and cut it in a circle for the top of the glass.  The piece of acetate needs to be larger in circumference than the glass though.  Place the acetate on top of the glass and turn the glass over.    Explain why the water doesn't escape.  The answer might surprise you.  A hint is because of pressure but how much is there, where does it come from, and what is its dimension?

Trees do NOT get water to their leaves using cappilary action alone. Cappilary action could lift water to maybe 10 metres maximum. The tallest trees are over 8 times that height. Cappilary action plays only a small, albeit vital, role in lifting water in trees.\n\nThe simple answer is that the tree uses the equivalent of a siphon effect to lift the water. A siphon works because water is cohesive, IOW water sticks to water. That cohesiveness of water in a siphon tube means that as water at one end falls it is able to suck more water up from the other end. Provided that the fall is greater than the rise you are trying to overcome you can use a siphon to lift water to significant heights.\n\nA tree trunk is basically composed of masses of siphon tubes filled with water, but it doesn't have any physical 'fall' component. Instead what the tree uses is the force generated by evaporation. As water enters a leaf it is exposed to the air and allowed to evaporate. Because water is cohesive that loss of water creates a negative pressure that pulls more water into the leaf within the leaf, and that in turn creates a negative pressure that pulls water into the vessel elements of the branch and the trunk. That pressure is sufficiently high to lift water to the tops of the tallest trees.\n\nWhich is why trees use such massive quantities of water. Even a small tree will use over 100 litres of water a day and less than 1% of that will be used physiologically. The rest is simply evaporated off to draw more water up the stem. It's an incredibly wasteful process.\n\nThis is also the reason why trees in dry environments are invariably shorter than plants in wetter environments. Because the system functions like a siphon the water column in the trunk can never be allowed to break or the pressure inside will immediately drop to zero. It's like getting vapour lock in a fuel line and plants can't re-prime the line. There has to always be sufficient water in the ground to feed the negative pressure required in the column. The taller the tree the greater pressure required and hence the more water required. As a result the maximum height of tree is determined in large part by the amount of water available.

Sorry but to divulge Genters location would be futile.  Attempts made at this, will result in your molecules being vaporized and then transformed into 46c4 carbon based atoms, which will then be erased

I agree with answer one... depends on the size of the container\nThe spherical shape has the minimum surface area for a given volume (in this case for a given number of molecules, since each molecule occupies the same amount of volume).\n\nThis is why a drop of water is spherical. If we distort the drop, it “wants” to come back to its spherical shape, and the force pulling it back is what we call surface tension creating a meniscus. \n\nThis tension acts in a similar way as the stretched rubber in a balloon: if we distort the balloon and then release it, it comes back to the spherical shape.

Oh yes@!\n\nCheck the article "Scientists make water run uphill " below\n\nand water can also run up hill \n\ncase 1 capillary motion due to surface tension (in plants)\ncase 2 siphon arrangement  \ncase 3 difference in pressure (as in fountain...)\n\nand artificialy\nmay be there is even case 4 if you want to get some polymers involved http://www.stevespangler.com/archives/2006/02/08/water-can-run-uphill/\n\nFor an instace of case 3 check this out http://www.iit.edu/~smile/ph87t2.html \n\nAnd superfluid don't really run uphill http://www.madsci.org/posts/archives/feb98/888462465.Ph.r.html

Atmospheric pressure will support a column of air about 10 metres high.   The exact height varies from day to day depending on atmospheric pressure; high and low pressure systems.   To start with, partly fill your container with coloured water, with the hole at the bottom submerged in more coloured water.   If there was no air in your transparent ball, it would need to be 10 metres in diameterfor you to see a boundary between the empty space at the top and the water column supported by the atmosphere pushing down on the liquid outside, but because you've trapped some air inside, this air pushes down on the water so the water isn't as high.
