This is probably an example of the sort of ambiguity which is the reason 'physical' and 'chemical' changes tend not to be mentioned outside of early science education.
The exact physical make-up of the solute (nail polish) is not changed, but chemical bonds are both broken and made in this process (various intermolecular bonds). The reaction is reversible, but then, all chemical reactions are reversible, but require extra energy put into the system to reduce the entropy.
Probably the best approximation would be to say it is a physical change, since all/most of the molecules involved are structurally unchanged.
it is a physcial change.. had it on a Chem 104 exam... def physcial
nail polish is a physical change because it changes from wet to dry
It is physical change
Chemical change

It depends on the composition of the rock, but the answer is "yes," abrasion can polish rock surfaces.
Nail Polish Removers

abrasion
good fraction contain provide lubricating oils.
hammering a nail is a physical change, this is because the nail changes shape from being long to being short and in a board for example.
The chemical compounds that make up the clear liquid kills your nail
It depends how you mean dull. Dull by wear or dull by oxidation? If it just becomes dull without being touched, then it is a chemical change. Metals readily react with non metals ie Oxygen. This will form a metal oxide layer on the exposed regions. This is why you need to sandpaper down some of the more reactive metals, when using them for conductivity experiments in school, as the oxide reduces conductivity.
because nail polish is soluble in spirit
Nail polish remover contains acetone which is a very good organic solvent. It dissolves the nail polish and helps to clean it off.
No. Everything that has mass and volume is a chemical or a part of a chemical. Chemical free shoe polish would have to be some form of energy.
Yes, acetone dissolving and removing nail polish is a physical change because the chemical composition of both substances remains the same before and after the process.
There is a solvent that is marketed specifically for the purpose of removing nail polish, which is called nail polish remover. It works. Buy a bottle.
Nail polish is a chemical compound, a solvent as acetone for example.
because spirit absorbs the particals of nail polish and the surface of the nails look like pearl
There are various techniques of removing liquid black shoe polish from concrete. You can use rubbing alcohol or dry-cleaning fluid to wipe of the polish from your concrete.
is ACETONE an ketone compound
