Changing States Of Matter
If you’re confused about chemical and physical changes and how to tell them apart, you’ve come to the right place. Chemical and physical changes are changes in the structure of matter. In a chemical change, a chemical reaction occurs and a new substance is produced. In a physical change, the form of a substance changes but does not change its chemical identity. Therefore, the difference between chemical and physical changes is that chemical changes change the chemical composition of the material, while physical changes do not.
A chemical change produces a new substance, while a physical change is important but not its chemical identity.
Chemical changes involve chemical reactions to produce new products. This is a change at the molecular level. Chemical bonds between atoms break and then form to connect different atoms.

In a chemical change, the atoms arrange themselves. Chemical bonds are broken and converted into new molecules. Examples of chemical changes include:
A physical change is a change in matter that changes its form but not its chemical identity. The shape or size often changes, but there is no chemical reaction. Phase change is a physical change. These include melting, boiling, steaming, freezing, thawing and freezing. Material destruction, grinding or molding also causes physical changes. Many physical changes are reversible.
The key to distinguishing between chemical and physical changes is determining whether there is a new substance that did not exist before. If you see signs of a chemical reaction, it is a chemical change. Symptoms of a reaction include:
Some people use nausea as a test for chemical and physical changes. The proof is that physical changes are reversible, while chemical changes can only be reversed by another chemical reaction. This is not a good test because there are many exceptions. While you can melt and freeze cubes, shredding paper (another physical change) is difficult to reassemble.
The Classification Of Matter
Most physical changes are reversible if energy is added. Some chemical changes are reversible, but only through another chemical reaction. For example, rusting iron is a chemical change. You can turn rust back into iron and oxygen, but it requires a chemical reaction.
