Crushing a diamond is a physical change because the substance is the same just the appearance isn't,
I think it would be a physical property, since no new substance was made, and it is re-versable. There was only a change in the form.
This is a physical action.
yes
Physical property
Both chemical -- carbon, and physical -- 10 on the Mohs Scale of hardness for minerals.
Cutting bread is a mechanical or physical change, not a chemical change.
With scissors: definetely physical, you don't cut the molecules in hair themselves
Cutting doesn't change the chemical composition.
Yes, it is undoubtly physical itself. The cause of easy breaking eg. after chemical detoriation of its fibrous structure by molds can be chemical. The force by which it's breaking (wind, gravity) is physical however.

cutting your hair is probably a physical change I don't know
Yes it is a phisycal change because even though you cut the carrot in half its still a carrot. You're not changing the substence you are just changing what it looks like no cutting carrotis not a physical change no cutting carrotis not a physical change
It is a physical change.

Do the logs change from wood to some other substance? No, so it has to be a physical change.

Cutting a rope is a physical change. Burning a rope, or disolving it in acid, would be a chemical change.
