• Properties Changes in Matter
• Extensive vs. Intensive
• Physical vs. Chemical

2
Extensive vs. Intensive

• Extensive Property
• depends on the amount of matter present
• Intensive Property
• depends on the identity of substance, not the
  amount

Physical vs. Chemical

• Physical Property
• can be observed and measured without changing the
  identity of the substance
• Chemical Property
• can be observed by changing the identity of the
  substance

Physical vs. Chemical

• Physical Change
• changes the appearance of a substance without
  changing its identity
• properties remain the same
• Chemical Change
• changes the identity of a substance
• products have different properties

7
Physical vs. Chemical

• Signs of a Chemical Change
• change in color or odor
• formation of a gas (bubbling, fizzing)
• formation of a precipitate (a solid that
  separates from solution)
• change in light or heat
