1 I. States of Matter Kinetic Molecular Theory States of Matter
Ch. 1 - Matter I. States of Matter Kinetic Molecular Theory States of Matter

2 A. Kinetic Molecular Theory
KMT Particles of matter are always in motion. The kinetic energy (speed) of these particles increases as temperature increases.

3 B. Five States of Matter Bose-Einstein Condensate
Atoms mount on top of each other

4 B. Four States of Matter Solids
very low KE - particles vibrate but can’t move around fixed shape fixed volume

5 B. Four States of Matter Liquids
low KE - particles can move around but are still close together variable shape fixed volume

6 B. Four States of Matter Gases
high KE - particles can separate and move throughout container variable shape variable volume

7 B. Four States of Matter Plasma
very high KE - particles collide with enough energy to break into charged particles (+/-) gas-like, variable shape & volume stars, fluorescent light bulbs, CRTs

8 II. Classification of Matter Matter Flowchart Pure Substances Mixtures
Ch. 1 - Matter II. Classification of Matter Matter Flowchart Pure Substances Mixtures

9 Can it be physically separated?
A. Matter Flowchart MATTER yes no Can it be physically separated? MIXTURE PURE SUBSTANCE Is the composition uniform? no yes Can it be chemically decomposed? no yes Homogeneous Mixture (solution) Heterogeneous Mixture Compound Element Colloids Suspensions

10 A. Matter Flowchart Examples: graphite element pepper hetero. mixture
sugar (sucrose) paint soda element hetero. mixture compound solution

11 B. Pure Substances Element composed of identical atoms
EX: copper wire, aluminum foil

12 B. Pure Substances Compound
composed of 2 or more elements in a fixed ratio properties differ from those of individual elements EX: table salt (NaCl) Ionic vs Molecular compounds

13 B. Pure Substances Law of Definite Composition
A given compound always contains the same, fixed ratio of elements. Law of Multiple Proportions Elements can combine in different ratios to form different compounds.

14 Two different compounds, each has a definite composition.
B. Pure Substances For example… Two different compounds, each has a definite composition.

15 C. Mixtures Variable combination of 2 or more pure substances.
Can be separated by physical means. Distillation, density, filtration, magnetism, boiling points Homogeneous Heterogeneous

16 C. Mixtures particles don’t settle EX: rubbing alcohol Solution
Tyndall Effect Solution homogeneous very small particles no Tyndall effect particles don’t settle EX: rubbing alcohol

17 C. Mixtures Colloid heterogeneous medium-sized particles
Tyndall effect particles don’t settle EX: milk

18 C. Mixtures Suspension heterogeneous large particles Tyndall effect
particles settle EX: fresh-squeezed lemonade

19 C. Mixtures Examples: mayonnaise colloid muddy water suspension fog
saltwater Italian salad dressing colloid suspension solution

20 Ch. 1 - Matter III. Properties & Changes in Matter
Extensive vs. Intensive Physical vs. Chemical

21 A. Extensive vs. Intensive
Extensive Property depends on the amount of matter present Intensive Property depends on the identity of substance, not the amount

22 A. Extensive vs. Intensive
Examples: boiling point volume mass density conductivity intensive extensive

23 B. Physical vs. Chemical 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

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

25 B. Physical vs. 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

26 B. Physical vs. Chemical Signs of a Chemical Change
change in color or odor formation of a gas formation of a precipitate (solid) change in light or heat

27 B. Physical vs. Chemical chemical physical rusting iron
Examples: rusting iron dissolving in water burning a log melting ice grinding spices chemical physical

28 Intro to periodic table
Groups (Families) Periods Noble Gases Metals vs. Nonmetals Metalloids (B, Si, Ge, As, Sb, Te) Alkali Metals Halogens
