Mix them all together, shake, and let them settle out. The liquids on the bottom will be the most dense, and hte ones on top the least.

You know you could just look it up. :) But I can help with a few I guess: 2- the particles would move faster. 3- false. 9- Weight. 14- thick, slow. 17- false. That is all I can or will help you with.

Mix them together The one that sinks is more dense.

DENSITY: - is weight or mass per unit volume and is found by the formula :-
Density: = Weight (Mass) ÷ Volume (or W / V)
Where weight (mass) is given in Pounds, Grams, Kilograms .. etc. and Volume in Cubic feet, Cubic metres, Litres, gallons .. etc.
Therefore, Density is expressed as :-
Pounds per cubic foot (Lb/ft³); Pounds per gallon (Lb/gal); Grams per litre (g/l) or Kilograms per cubic metre (kg/m³) .. etc.
Density is measured at standard conditions of temperature & pressure: i.e. Atmospheric pressure and 60°F (15.6°C).
Liquid density is generally measured in lbs/gal (Imperial),
or kg/m³ (S.I.).
Pure water density is known to be 10 lbs/gal (Imperial), &
8.3 lbs/gal (U.S.) and, in S.I Units, 1000kg/m³ ( or 1g/cc)
Density of liquids (& solids) are compared to the density of pure water. These comparisons are referred to as 'Specific Gravity'
(S.G.) or 'Relative Density' (R.D.).
To find the S.G. of water we compare the density of water to the density of water (sounds daft, but necessary).
S.G. of Water = Dw (10lbs/gal) ÷ Dw(10lbs/gal) = 1.000. (The units cancel out)
We will now compare other liquids and find their S.G's.
S.G. of liquid = D liquid (lbs/gal) ÷ D water (lbs/gal).
Let us use Kerosine as our example.
From tables we can find that Kerosine density is 6.70 lbs/gal
We now have: D liquid 6.7 lbs/gal ÷ D water 10 lbs/gal. (Again, units cancel)
S.G. Kerosine = 6.7 ÷ 10 = 0.670. This tells us that Kerosine is lighter than water (which is 1.000).
If we look up the S.G. of Mercury, we will see it's 13.6 (meaning it is 13.6 times heavier than water, which is 1.000).
1 gallon of mercury will weigh: 13.6 x 10 = 136 lbs
So Density of any liquid = S.G. of liquid x 10 = lbs/gal
(I hope you have followed this OK !)
