• Use a Venn diagram to compare solids,
liquids, and gases, based on shape,
volume, and whether or not they are
easily compressed (or forced into a
Properties of Matter
1.1 Distinguishing between intensive and
extensive properties of matter
Other AOD C.8.3 Compare chemical and
physical properties of matter.
1. Water + alcohol
2. Marbles + water
• Can anything else be added to the
marbles and water?
• Relationship to solids, liquids, and
Gas and Vapor
• “Gas” applies to substance that is
naturally in the gaseous state at room
• “Vapor” is the correct term for the
gaseous state of a substance found in the
solid or liquid state at room temperature.
• What is steam?
“Matter” and “Substance”
• Define “matter”.
• Def.: anything that has mass and takes up
• Def. of substance: matter that has a
uniform and unchanging composition.
• In my words: Substance is matter that has
a chemical formula (i.e., H2O or NaCl)
• What about pool water or ocean water???
• Def.: a characteristic that can be
measured or observed without changing
the sample’s composition
• Name some physical properties of a
• Name some physical properties of a rose.
• May include density, color, odor, taste,
hardness, conductivity, malleability,
shape, mass, length, volume, melting
point, boiling point, state of matter at
Extensive vs. Intensive
• Extensive properties are dependent upon
the amount of substance present.
• Intensive properties are NOT dependent
upon the amount of substance present.
• Use the list of physical properties from
the previous slide, and classify each
property as either extensive or intensive.
• Def.: the ability (or inability) of a
substance to combine with or change into
one or more other substances
– What happens to iron when exposed to air?
– Iron exposed to nitrogen?

and chemical properties of copper are
evident in these photos?
