What takes up more space-a kilogram of sawdust or a kilogram of iron?
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.
How can you separate sawdust from gravel?
Place the sawdust and gravel mixture in water and stir. Let it sit for a time - the gravel will fall to the bottom and the sawdust will float on the top. Density of gravel is greater than water and density of sawdust (wood) is less than water. The layer of sawdust can be carefully removed by skimming it off water's surface or by pouring gravel and sawdust through a series of mesh screens of varying size (the screens can be used with dry or wet mixture)I would use the difference in density of the two materials. A simple method would be to have a stream of the mixed materials poured from a higher elevation to a lower, with a stream of air blowing across the stream. Being less dense, the sawdust will be blown to one side, the gravel will drop straight down. Of course, you COULD just drop the mixed materials into water- sawdust floats, gravel does not. Sawdust will also burn, where gravel will not. Roasting the gravel at a heat above the combustion point of sawdust will cause it to ignite, burning the sawdust away, leaving gravel. Of course, if you have plenty of time, just turn a few termites loose on the mix- they will eat wood- but not gravel!
