A physical change is one where no new substance is produced. Melting is an example of a physical change. When you melt iron, you get liquid iron, it's still the same chemical substance. If you melt copper, you get liquid copper, not liquid iron.

This is a physical change. You only change the shape and size of an apple by slicing it. Chemical changes would mean changing the molecular composition of the apple.

no, that's would be a chemical change :) .
If you mean a change in chemical identity, that would be a chemical change.

Crumple is a physical change.
Water is not a reaction at all. If you mean to ask if a state change in water is chemical or physical, it is physical.
If you mean ground flour, then no. Grinding flour is a physical change because there is no change in chemical composition.
i mean change
Physical
yes it is because it is not changing the substance. EDIT: yes it is what? Is it chemical or physical? You probably mean it is a physical change.
