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

3. Extensive vs. Intensive
Examples:
boiling point
volume
mass
density

intensive
extensive

4. 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

5. Physical vs. Chemical Examples: melting point flammable density
magnetic
tarnishes in air
physical
chemical

6. 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
