Chemical change: the structure of the molecule is chenged.
Physical change: the structure of the molecule is not changed.
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.

A physical change is reversible, a chemical change is not.
A chemical change results in a change in chemical composition, while a physical change does not.
a physical change is reversible but a chemical change is irreversible
a physical change is reversible but a chemical change is irreversible
Physical change is a change in the structure. Chemical change is a change in the composition. Melting is a physical change. Complexing is a chemical change.
chemical
The diffence between chemical and physical is that ones chemical and ones physical!!
Physical
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
