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.
Painting your nails would be a physical form because you are adding the polish to your nails, but the nail remains the same. If you were to apply the nail polish and the nail melted, then that would be a chemical change because it creates something that can not be reversed. Physical changes can get the substance/object back to the way it was before. Ice is a physical change, it was water, it froze, and then it can melt again.
It is a physical change because it might change to a different color if rubbed
Physical. It's not like the clipped toenail has become another substance, has it? A chemical change requires that another, new substance has been created, and this requires a reaction.
Physical.
No new chemical bond has formed... therefore its not a chemical change.
Just the shape of the object has changed, and this is a physical change.
A nail rusting is a chemical change. Iron metal combines with oxygen from the air to produce iron oxide.
That's a physical change. Assuming the nail is made of iron (Fe), when you bend it, you simply change its shape. You don't change the fact that it's still iron.
What happens to a nail in acid is a chemical change because new substances are formed. If the nail is iron, and the acid is hydrochloric acid, then iron chloride and hydrogen are formed.

It is a chemical change
Chemical change, oxygen binds with iron.
chemical change
because the chemical composition of the nail is changed, forming a new substance (the rust)

Physical, if you are not using any chemicals in the process it is a physical change.
iron nail
Heating is a physical change.
A nail rusting is a chemical change. The chemical formula of the metal completely changes, adding oxygen to the formula. Iron changes from Fe to FeO2 , or to Fe2O3
Because the Iron in the nail is no longer just iron but oxidation plus iron, a physical change to the nail would be to cut it in-half.
Chemical change, oxygen binds with iron.
