Physical Propertiesare used to identify objects.
Can be measured or observed.
Physical properties
• Appearance• Color• Size• Shape• Odor• Weight• Density• Solubility
Volume measured by displacement
Volume = L X W X H
Volume – amount of space an object occupies
Each box has the same volume. Which box has the greatest density?Density is the amount of mass in an object.
Boiling Point – 100 degrees Celsius 212 degrees F

Mass is the amount of matter in an object.
An element is a pure substance made up of only one kind of atom.
