6. 2 of 2
Compressed Gas
(Class A):
Poses an explosion danger
because the gas is under pressure
Container may explode if heated in
a fire, or dropped

8. 2 of 2
Combustible and Flammable Materi
(Class B):
Will burn and is therefore a potential fire hazard
May burn at relatively low temperatures;
flammable materials catch fire at lower
temperatures than combustible materials
May burst into flame spontaneously in air, or
release a flammable gas on contact with water
May cause a fire when exposed to
heat, sparks, or flames, or as a result of friction

10. 2 of 2
Oxidizing Material
(Class C):
Poses a fire and/or explosion risk in the
presence of flammable or combustible
material
May react violently when it comes into
contact with combustible materials such as
fuels or wood
May burn skin and eyes upon contact
2003
12. 2 of 2
Poisonous and Infectious Material
(Class D, Division 1):
Is a potentially fatal poisonous substance
May be fatal or cause permanent damage
if it is inhaled or swallowed or if it enters the
body through skin contact
May burn eyes or skin upon contact
2003
14. 2 of 2
Poisonous and Infectious Material:
Other Toxic Effects (Class
D, Division 2):
Not immediately dangerous to health
May cause death or permanent damage as a
result of repeated exposure over time
May be a sensitizer, which produces an
allergy
May cause cancer, birth defects, or sterility
2003
16. 2 of 2
Poisonous and Infectious
Material:
Biohazardous, infectious material
(Class D, Division 3):
May cause a serious disease
resulting in illness (AIDS, Hepatitis)
or death
Can also include tetanus
protection
2003
18. 2 of 2
Corrosive Material
(Class E):
Causes severe eye and skin
irritation upon contact
Causes severe tissue damage
with prolonged contact
Often produces vapor or fumes
that may be harmful if inhaled
2003
20. 2 of 2
Dangerously Reactive Material
(Class F):
Is very unstable
May react with water to release a toxic
or flammable gas
May explode as a result of
shock, friction or an increase in
temperature
May explode if heated when in a closed
container

24. A pure substance is a material whose
properties are not a blend and are always
the same
Ex. Gold, Silver
Apure substance must be
HOMOGENEOUS
25. Allpure substances are homogeneous, but
all homogeneous mixtures are not pure
substances
There are two types of materials;
• Homogeneous
• Heterogeneous
26. Homogeneous – Mixture that looks like it is
one material
• Coke – Cola, Milk
Heterogeneous – when the parts are
visibly different
• Chocolate Chip Cookie
27. A mixture that looks like one material but
is very difficult to separate
• Ketchup, Milk
28. is
a heterogeneous fluid containing solid
particles
29. The solubility of a substance is the amount
of that substance that will dissolve in a
given amount of solvent
Has two parts;
• Solute -- What is being dissolved
• Solvent – The dissolving substance
30. Thepoint where no more solute can be
dissolved into a given solvent at room
temperature
Super-Saturation – When more solute is
dissolved in a solvent than normal
31. Temperature
• When the temp. goes up in a liquid so does the
solubility
• When temp goes up in a gas, the solubility goes
down
32. ACRONYMN to remember it
S – Spaces between particles
P – Particles – all matter is made of it
A – Attraction – attracted or bonded to each other
M – Movement of particles (always
moving)
33. Thehigher the viscosity the thicker the
substance is
Thelower the viscosity the thinner the
substance is
34.
35. Liquidcannot be as compressed as much
as gas because the spaces between the
particles are not as far apart.
36. Divide
the amount of your solute into your
amount of solvent
Ex.
13g of salt is dissolved into 50ml of
water
13g/50ml
37. TO solve for density you must use the
following equation;
Density = mass/volume
38.
39. When in a liquid, the force of gravity pulls it
down,
• The liquid releases an opposite force to gravity
called BUOYANT FORCE, pushing the object
upwards
Ifthe liquid the object is in is more dense
the buoyant force is greater than gravity
and the object floats
41. KNOW ALL OF THE ORGAN SYSTEMS
• Digestive
• Respiratory
• Circulatory
• Excretory
• Nervous
42. Food Passage
• Mouth – Esophagus – Stomach – Small intestines
– large intestines – anus
• Villi – hair like projections in the intestines that
catch nutrients
43. Parts
• Mouth – trachea – Bronchi tubes – bronchiole –
alveoli
• Gas transfer – Oxygen in, Carbon Dioxide Out
• What are the concentrations of the gases in the
alveoli
44. Arteries carry blood away from the heart
Platelets help form blood clot
Pathway of blood to the heart
• Arteries – veins – right atrium – left ventricle –
lungs – right ventricle – right atrium -- arteries
45. Each organ involved and what they do
• Liver, kidneys, bladder, urethra, ureter
• What is UREA – Waste products of the body
46. Organs
• Brain, Spinal cord, nerves, dendrites, axons
• PNS/ CNS – organs that go with each
48. Xylem – dead cells that transport water in
a plant
Phloem – Living cells that transport food
and nutrients throughout the plant
49. Base
Lens
Coarse/fineadjustment knob
Diaphragm (where the light gets in)
50. 4 types –
• Connective – connects one body part to another
• Muscle – is able to contract and carry electrical
impulses
• Nervous – Makes up the CNS and PNS
• Epithelial – Skin cells
51. Diffusion– transports oxygen from your
blood into your cells, and carbon dioxide
from your cells into your blood
Osmosis – Water going from high
concentration to low concentration
Permeable Membrane – a
Selectively
membrane that allows only certain
substances through
52. Plasma is made up of;
• The liquid portion of your blood,
