I.Properties & Changes in Matter Extensive vs. Intensive Physical vs. Chemical
Extensive Property depends on the amount of matter present Intensive Property depends on the identity of substance, not the amount
Examples: boiling point volume mass density conductivity intensive extensive intensive
Physical Property can be observed without changing the identity of the substance Chemical Property describes the ability of a substance to undergo changes in identity
Examples: melting point flammable density magnetic tarnishes in air physical chemical physical chemical
Physical Change changes the form of a substance without changing its identity properties remain the same Chemical Change changes the identity of a substance products have different properties
Signs of a Chemical Change change in color or odor formation of a gas formation of a precipitate (solid) change in light or heat
Examples: rusting iron dissolving in water burning a log melting ice grinding spices chemical physical chemical physical

I. Properties of Matter Matter is defined as anything that has mass and takes up space. The mass of an object is the amount of matter that the object.
Do Now #7 A physical change occurs when a substance changes form, but stays the same. A chemical change occurs when a substance changes into a new, different.
