3. What branch of science is the study of matter?

Matteris anything with mass and volume

that is made of ATOMS

Section 2.1 Notes: Matter

…a quick review…

• MASS: a measure of the amount of matter present (measured in grams)

• VOLUME: a measure of the amount of space something occupies (measured in m3 or liters)

Matter can be found as:ELEMENT a pure

substance made of ONE kind of atom.

COMPOUND substance made from the atoms of 2 or more different elements that are stuck together (bonded).

Elements are found on the periodic table.

MIXTURES• Mixtures are composed of more than one type of

substance mixed together.

• In a homogeneous mixture, the mixture looks uniform throughout – Examples: salt water, lemonade, chocolate ice cream– Also called solutions

• In a heterogeneous mixture, the mixture is not uniform – Examples: trail mix, granite, chocolate chip ice cream
