A physical change doesn't modify the chemical nature of the molecule.
A chemical change transform the molecule A in another molecule B.
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.
Physical property is an aspect of matter that can be observed or measured without changing, Chemical property may only be observed by changing the chemicals identity of a substance. (this was copied off a scientific website) :)
a physical change is reversible but a chemical change is irreversible
You can tell the difference by knowing that a physical property changes shape and that a chemical property changes the substance.
it can bereversible and
Your telling me!
the difference is chemical can change it and it cant go back to normal. physical is when u can put it back.
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...)
The difference is that chemical equilibrium is the equilibrium of products and reactants in a reaction while physical equilibrium is the equilibrium of the physical states of the same substance.
