Properties are used to identify substances.2.32.3
SECTIONOUTLINESECTIONOUTLINE
Physical properties that can be used to identify substances include:
• density
• heating properties
• solubility
• electric properties
• magnetic properties
Mixtures can be separated by using the properties of the substances they contain.
