When two substances combine and retain their own properties, a mixture results.
The smallest particle of a substance that retains all the properties of the substance and is composed of one or more atoms is a molecule.
When a substance changes but still retains its original properties, the change is called a physical change. If it didn't retain its original properties, then it went through a chemical change.
