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'.
What is a sign that a chemical change has occurred smoke broken pieces change in shape or change in state?
The production of smoke from something burning would be a sign of a chemical change. Broken pieces, change in shape, or change in state are all physical changes.
HOW TO Prepare alum from scrap aluminum?
To prepare alum from scrap aluminum, begin by cutting the aluminum into small pieces and dissolving it in a sodium hydroxide solution. Filter out any impurities, then add sulfuric acid to the solution to precipitate aluminum hydroxide. Lastly, treat the aluminum hydroxide with sulfuric acid and allow the solution to evaporate to obtain alum crystals.
Is wood being slit in two pieces phyiscal change or chemical change?

Is tearing a clothes into pieces a physical or chemical change?

Why do the pieces of aluminum foil have different masses?
Because all aluminum foil is not equal. Aluminum foil is available in a variety of thicknesses.
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.
Is aluminum foil cut in half a physical or chemical change?
Cutting aluminum foil in half is a physical change. A physical change alters the form of a substance without changing its chemical composition. In this case, the aluminum foil remains aluminum foil after being cut in half, just in two smaller pieces. No new substances are formed during this process, so it is considered a physical change.
What happens to pieces of aluminum in a pile of scrap metal when an electromagnet nears the pile?
If the aluminum has iron attached to it it will be picked up by the magnet otherwise it will remain on the ground.
If a cube of Jello is cut into two pieces what property of the pieces did change?

Does aluminum shatter or bend when hit with a hammer?
Aluminum tends to bend rather than shatter when hit with a hammer due to its malleability. The metal is softer and more ductile compared to brittle materials like glass or ceramics, allowing it to deform and change shape instead of breaking into pieces.
Is aluminume foil cut in half chemical or physical?
Foil cut into pieces represents a physical change.
Are there 1953 aluminum pennies?
No. The only cents ever struck in aluminum were some test pieces made in 1974. None are know to have been put in circulation.
Can you give a sentence using the word rivet?
The two pieces of aluminum are held together with a single rivet. Rivet here is a noun, as it is the name of a type of fastener. Rivet the two pieces of aluminum together. In this instance it is a verb, to rivet, the action of riveting.
Could you tear aluminum foil forever always producing smaller pieces?
No, not and still have aluminum. At some point you will have divided it so finely that all you will have is a single atom of aluminum. That atom is the smallest quantity of the metal that exists.
