2

Intensive property

________- a property that depends on the type of matter in a sample, not the amount of matter (ex.

New cards
3

Homogenous solution

________- denoted by (aq), which means aqueous (NaCl (aq))

New cards
4

Heterogeneous mixture

________- a mixture that is not uniform in composition.

New cards
5

definite volume

Solid- has a(n) ________, has a definite shape (atoms are packed together in fixed positions, strong attraction forces between atoms, only vibrate in space)

New cards
6

matter

has mass and occupies space, meaning it has volume (a measure of the quantity of matter, density)

New cards
7

phases of matter

solid, liquid, gas

New cards
8

solid

has a definite volume, has a definite shape (atoms are packed together in fixed positions, strong attraction forces between atoms, only vibrate in space)

New cards
9

liquid

has a definite volume, has an indefinite shape (atoms are close together, atoms can overcome attractive forces to flow)

New cards
10

gas

has no fixed volume, has no definite shape (conforms to the volume and shape of a container, can compress to occupy a smaller volume and expand to occupy a larger volume, fairly weak attractive forces)

New cards
11

physical properties

properties that can be measured or judged without changing the basic identity of the substance (color, odor, hardness, density, melting point, boiling point)

New cards
12

mixture

refers to the combinations of two or more substances in which each substance retains its own chemical identity (can be evenly distributed or unevenly distributed, different states of matter can form mixtures, physically combined, can be mixed in any proportion)

New cards
13

homogenous mixtures

a mixture that is uniform throughout in its consistency
