Intensive/Extensive

There are two categories of physical properties:
1) Intensive
2) Extensive

Intensive
Intensive properties are properties that are independent of the amount of matter present.

Ex.

Color - your hair remains the same color after you cut it (decrease the amount of matter present)

DENSITY - density is a ratio and does not change if the state of matter remains the same

Odor - 1/2 of a lemon smells like a lemon, 1/4 of a lemon smells like a lemon

Boiling point - 100 mL of water will boil at 100 degrees F, 200 mL of water will boil at 100 degrees F

Freezing point - 100 mL of water will freeze at 0 degrees F, 200 mL of water will freeze at 0 degrees F

Extensive
Properties that depend on the amount of matter present.

Ex.

Measurements - if I cut a 6 inches straw in half (remove matter), it is no longer 6 inches

Mass - if I remove 5 g from a 10 g sample (remove matter), it no longer weighs 10 g

Volume - if I add 10 mL to a 5 mL (add matter), it no longer has a volume of 5 mL
