Answer:
it could not be used because it can attracts the magnets in which compass it self is a form of magnet which can utilize the magnetic properties of the earth to give a reading and Compass housings are often made of either brass, aluminium or plastic.
Explanation:
The characteristic of iron that would make it a bad material for the housing around a compass is that it could not be used because it can attracts the magnets in which compass it self is a form of magnet which can utilize the magnetic properties of the earth to give a reading reason been that Compass housings are often made of either brass, aluminium or plastic
Secondly it would confuse the magnet thereby making it un-useful or useless because the iron can easily become magnetized itself and Iron is a magnetic metal which can cause the needle of a compass to give a false reading thereby messing up the magnet's direction and making it useless.
I am mostly sure the answer is B. Good luck, and sorry if it's wrong! :(

Diffusion occurs because of the movement of molecules from the region of higher concentration to the region of lower concentration. This movement of molecules occurs due to a thermal motion. Diffusion normally occurs between two compartments having difference in concentration. In case of fluid it moves from the region of higher concentration to the region of concentration until a balance is reached. The process of diffusion is very important for the humans as well. The oxygen that humans breathe in gets diffused with the blood.<span>
