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.

∙ 13y agoPhysical 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.

∙ 14y agoA 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.

What is the difference between chemical change and physical change?
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.
What is the difference between a physical and chemical change?
A physical change is reversible, a chemical change is not.
Difference between chemical and physical change?
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...)
What is the difference between a chemical and a physcial change?
chemical change is easily reversible whilst physical is not reversible
What is the difference between chemical change and a physical change?
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

What is the difference between a physical and a chemical change?
Physical change is homogeneous and vise versa for change (heterogenous)
What is one major difference in a physical change and a chemical change is?
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.
