Is grinding a piece of aluminum a physical change or a chemical change?
It is a physical change since there is no reaction or any sort of change to the bonds, or the chemical make up of the aluminum. The only difference is that you have smaller pieces of aluminum after grinding, thus a physical change. -edit- THIS IS ALMOST A TRICK QUESTION. If the question asked if 'fileing' a piece of aluminum, THEN the above answer is absolutely correct. But the question said 'Grinding', and so you have to look at the actual process of grinding. When you are fileing you are usually using a hardened piece of metal cut so that it presents an abrasive surface. You scrape the file against the aluminum piece so that it literally cuts off small slices or fragments of aluminum and leaves you with a shiny pile of clean aluminum 'dust' below. When you are grinding you are usually using a 'stone' wheel of some kind that is rapidly spinning and you 'burn' off aluminum that you want to remove. Its not actually burning but if you think of it that way, since its a huge shower of sparks usually, you can imagine it as a chemical change to the aluminum that is removed from the original piece. If you are able to search the floor for the 'burned' aluminum sparks that have cooled (dont burn your hand they are so hot) you will find 'chemically changed' aluminum 'residue'.

Can aluminum cans change from biomass to compost?
No, aluminum cans do not change from biomass to compost. Compost is dark-colored, fresh-smelling, nutrient-rich organic material. Aluminum is inorganic even though the element can rust and smash into such small pieces that it over a very long time supplements the elements (of which it is not one of the essentials) and minerals in soil.
