This is a tricky question. Perhaps reading: http://www.newton.dep.anl.gov/askasci/chem03/chem03067.htm will help.

Clearly the answer is water.  The reason has to do with the 'viscosity' (viscosity = resistance to flow) of the three fluids:\nhttp://en.wikipedia.org/wiki/Viscosity\n\nWater: low viscosity ─► marble moves quickly\nSyrup and Shampoo: high viscosity ─► marble moves slowly\n\nAlso look into 'Reynolds numbers':\nhttp://en.wikipedia.org/wiki/Reynolds_number

WHOA !!! you have a contradictory question..emulsification is NOT the same as solubility. What do you want to do ? Emulsify or dissolve ?

Click on "Add details," post the problem, and, as SMeghead said, someone might be able to help.\n\n(EDIT: You didn't provide too much information. From what you gave, about all we can say is that 12.5% of the solute - 1% from 8% - evaporated. If you need to know how many grams, milliliters, cubic centimeters, etc. evaporated, we'll need more information.)

I did a science fair project that combined science and economics - it was called "Which Dish Washing Liquid is Best for Your Buck".  I tested which dish washing liquid was the best by seeing how many drops of it were needed to destroy the surface tension of a glass of water.  I then figured out how much each drop of dish washing liquid cost, and reported on the best value.  The judges seemed to like the economics side of it as well as the science fair side of it.  Good Luck!

You can think of viscosity as referring to how much drag is exerted on a surface as the liquid flows by.  Generally, a thicker fluid has higher viscosity so I agree with your choice of honey.\n\nAs particles (molecules) become more loosely connected, the liquid flows more easily, so should be obvious how this relates to viscosity.

If the spheres are of same volume, their apparent loss of mass will be the same.\n\nIf the spheres are of same mass, Aluminium sphere's apparent loss of mass will be more.

a sol is colloid in which solid is dispersed in liquid.

I agree with colloid.

Colloid, suspension of tiny particles of one substance, called the dispersed phase, in another phase, called the continuous phase, or dispersion medium.\n\nBoth the suspended, or dispersed, phase and the dispersion medium may be solid, liquid, or gaseous, although the dispersal of one gas in another is not known as colloidal dispersion. An aerosol is a colloidal dispersion of either a solid in a gas (such as cigarette smoke) or a liquid in a gas (such as insecticide spray). An emulsion is a colloidal dispersion of liquid particles in another liquid; mayonnaise, for example, is a suspension of tiny globules of oil in water. A sol is a colloidal suspension of solid particles in a liquid; paints, for example, are a suspension of minute solid pigment particles in an oily vehicle. A gel is a sol in which the suspended particles are organized in a loose, but definite three-dimensional arrangement, giving some rigidity and elasticity to the mixture, as in jelly.\n\nThe particles of a true colloidal dispersion are so small that the incessant bombardment of the molecules of the medium is sufficient to keep the particles in suspension; the random motions of the particles under the influence of this molecular bombardment is called Brownian motion. If, however, the force of gravity is greatly increased in a high-speed centrifuge, the suspension can be broken and the particles made to settle.\n\nColloidal dispersions in liquids are produced industrially by intensive grinding of a solid in a colloid mill or by intensive mixing and whipping of two liquids together in an emulsifier; wetting of the suspended phase is aided by the addition of a wetting agent known as a stabilizer, a thickener, or an emulsifying agent.\n\nThe movement of colloidal particles through a fluid under the influence of an electric field is known as electrophoresis. One method of electrophoresis, devised in 1937 by the Swedish biochemist Arne Tiselius, is used to study proteins and to diagnose diseases that cause abnormalities of blood serum.\n\nBecause of their size, colloidal particles cannot pass through the extremely fine openings in a semi-permeable membrane, such as parchment, by osmosis. Although a colloidal dispersion cannot be purified by filtration, it can be dialysed by placing it in a semi-permeable bag with pure water on the outside. Dissolved impurities then gradually diffuse through the bag, while the colloidal particles remain imprisoned within it. If the process of dialysis is carried to completion, the suspension will often break down, or settle, because the stability of colloidal systems frequently depends on the electrical charges on the individual particles, and these are in turn generally dependent on the presence of dissolved electrolytes.\n\nAlthough individual colloidal particles are too small to be seen with an ordinary microscope, they can be made visible by means of an ultramicroscope, or dark-field microscope. If a colloidal dispersion is placed under a microscope and a beam of light is directed through from one side, the path of the beam becomes visible by scattering from the colloidal particles. This same phenomenon makes the path of a beam of light visible in a darkened room, but under the microscope separate flashes of light are observed. The particles are seen to be in random motion as the result of Brownian motion, and their speed is exactly that calculated for molecules the size of the colloidal particles.

When what is mixed is not fully disolved into the liquid medium.  It usually settles.  A cenrifuge will not separate out the components that are not part of the solution.

I think that what is troubling you could be an exerecise involving "molarity" which uses two quantities: mass(moles)/volume(liter). \nBut you have to bear in mind that mass is referred to the solute, and volume refers to the solution. So, these quantities are not referring to ONE substance. \nIt would be better if you posted a question with the whole exercise, for clarity. \nGood luck.

Here is a great lab on ferrofluids that I am familiar with. Some info about ferrofluids is in there, too.\n\nhttp://mrsec.wisc.edu/Edetc/nanolab/ffexp/index.html

colloid = any system involving two phases where one phase is dispersed in another... the dispersed phase is usually less than 1micrometre in particle size....eg....\n\nmayyonaise is an oil/water suspension;  photographic film is a colloidal suspension of silver halide

Probably carbon latice structures, like buckeyballs or nanotubes.  These could then contain the smaller compounds that are doing the desired work.

That question cannot be answered with the limited amount of information provided.  However,  if you consider the speed of the particles...then heat is the answer.  Considering anything else requires more information.
