A chemical change is the change of one or more substances into other substances. A physical change is when the state or shape of matter is changed. In a chemical change molecules are combined or beak apart to form new substances.Rusting iron is an example of a chemical change. crushing a can or tearing paper can be an example of physical change.
Physical change is what changes externally not relating to the composition of atoms and molecules. Physical change would be like a crack in a piece of granite rock. Chemical change is what atoms of molecules are changed like exchanging of electrons or ions between the atoms of the object. Or how is properties are changed or the atoms type changing like a radioactive decay turning atoms of uranium into an element with a lower atomic number would be a chemical change.
A physical reaction/change can be changed back to its original form. eg. Ice>water>steam. The stem can go back.
A chemical reaction/change cannot be changed back into its original form. eg. Bread>toast. You cant turn the toast back into bread.
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 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...)
chemical change is easily reversible whilst physical is not reversible
a physical change is reversible like freezing or melting but a chemical change is irreversible like baking a cake, once it's been cooked, you can't get your cake mix bake

A physical change is reversible, a chemical change is not.
a physical change is reversible but a chemical change is irreversible
a physical change is reversible but a chemical change is irreversible
The diffence between chemical and physical is that ones chemical and ones physical!!
what is the difference between a physical change and a physical property
A change of state is a physical change while a chemical change is not
Physical change is homogeneous and vise versa for change (heterogenous)
Physical change, changes the appearance or the surface. Chemical change, changes the minerals inside the object. Physical deals with the appearance and the surface. Chemical changes the structure of the minerals inside the object.
