They both weigh 1kg....... so they weigh the same,
They're both a kilogram..
The sawdust. Density is the property that relates mass and volume (density = mass/volume). So the more dense something is, the less space a fixed mass of that material will take up. As iron is considerably more dense than sawdust (or any solid wood for that matter) it will take up much less space.
Due to atmospheric pressure the weight of 10 kg of cotton is grater than 10 kg of iron.
Not sure if this is a serious question but...A kilogram is a unit of mass, or in this case, weight.A kilogram is a kilogram.One kilogram of anything is a kilogram.1 kg of iron = 1 kg of wool.
I don't know what "appears heavier" means. A kilogram of mass is a kilogram of mass. Appearance has nothing to do with it. The cotton is (probably) less dense than the iron and will occupy a larger volume, but that doesn't have anything to do with the vacuum part.
No, both weigh a kilogram
The kilogram is a measure of weight so they are the same, the volume would be different.

A kilogram is a kilogram, no matter what.
All you have to do is put a magnet over the mess of sawdust and iron fillings and the iron fillings will get stuck to the magnet. Then their seperated
A kilogram is heavier.
A kilogram is about 2.2 times heavier than a pound.
Iron is magnetic; so, the iron filling is pulled/ is attracted to the magnet. The sawdust is not magnetic, so it will stay where it is, and will eventually be separated from the iron and the magnet.
A kilogram is heavier. Kilo means 1000, so a kilogram is a 1000 grams. The prefix kilo~ denotes 1,000.
