When sawdust is heated in water, it can absorb the water and swell due to the cellulose fibers present in it. As the temperature rises, the sawdust may release some compounds into the water through leaching. However, sawdust itself does not dissolve in water but can undergo physical changes like softening and expanding.
Sawdust and iron filings can be separated using a magnet. Since iron filings are magnetic, they will be attracted to the magnet, while the sawdust will not. By moving a magnet over the mixture, the iron filings can be collected, leaving the sawdust behind. This method utilizes the distinct physical properties of the materials for efficient separation.
Sawdust is chemically the same as wood -- it has only undergone a physical change to grind it into small pieces. Just as wood, sawdust is composed of chemicals such as cellulose and lignin, along with water.
