Because iron is much more dense.
Density is mass divided by volume. If we assume the mass of the iron and the cotton is the same, you will find that the iron will occupy less space (less volume) than that of the cotton. The value of a mass divided by a small volume is higher than the value of the same mass divided by a larger volume. If we assume the volume of both the iron and the cotton is the same, you will also find that the mass of the iron will be higher than the mass of the cotton. The value of a large mass divided by a volume is larger than the value of a small mass divided by the same volume. In both assumptions, the value of mass divided by volume for the iron is higher than the value of mass divided by volume for the cotton. Since density is mass divided by volume, the density of iron is therefore higher than the density of cotton.
It depends how large the cotton candy is, but it takes a huge piece of cotton candy to weigh even one kilogram.
1 billion tons
If you want to determine the density of the cotton ball, then you must determine the volume of the fiber in relationship to the total volume.Density (grams per milliliter – g/mL) = Mass (g) ÷ Volume (mL); or d = m / V.Each cotton ball will be slightly different and you will have to do the math on your own. You could weigh 10 and then divide by 10.
Many things weigh less than a feather in the same way that a small stone is lighter than a large stone. This could include single hairs, snowflakes and short threadsIf you mean are there things with a lower specific gravity (mass per unit volume) than feathers, again yes. This could include aerogel, gases, and cotton fibres.
Golden Retrievers are large dogs. Males weigh 65-75 pounds while females weigh 55-65 lbs.
Your answer depends on the quantity of cotton wool -- absorbent cotton that you want to weigh.
A litre is a region of space (volume or capacity). It has nothing to do with weight.
Depends on the type of crab, some are small, some are large
less then you. :)
Volume does not weigh. The two are different characteristics of objects and there is no relationship between them.
That will vary significantly depending on the toppings and how much of them. Plain cheese pizza slices will weigh the least. It will also depend on the size of pizza (e.g. small, medium, large, extra large).
