a. true
b. false
a. meet specific performance requirements - ANSWER-PADI courses are performance-
based. This means that to be certified, I must...
a. meet specific performance requirements
b. spend a given number of hours in training
c. simply pay for the course
a. true - ANSWER-Failure to complete assigned independent study can create
significant delays, and my instructor may have to cancel and reschedule sessions until I
complete the assignment.
a. true
b. false
a. true - ANSWER-When diving in a new dive environment, two benefits of seeking an
orientation, supervision, and/or additional training are that it helps me avoid problems
and that it helps me enjoy the dive more.
a. true
b. false
There is a pressure change of 1 bar/ata for every 10 metres/33 feet of depth change. -
ANSWER-What is the pressure change for each 10 metres/33 feet of depth change?
As pressure increases, gas volume decreases and gas density increases. - ANSWER-
What is the relationship between pressure and the volume and density of air?
weight - ANSWER-Right now, you are under pressure exerted by the air in the
atmosphere that surrounds you. This is actually the __________ of the air.
, weight - ANSWER-Underwater, you're under more pressure because water also has
__________, which combines with the atmosphere's pressure.
one bar (metric) or one atmosphere (imperial — abbreviated ata) - ANSWER-At sea
level the pressure is fairly uniform, and is expressed as...
As depth in water increases, pressure increases. As depth in water decreases, pressure
decreases. - ANSWER-What is the relationship between my depth in water and the
pressure?
10 metres/33 feet - ANSWER-Because water is much denser and heavier than air,
__________ feet exerts the same pressure as the whole atmosphere.
Pressure increases by one bar/ata for each 10 metres/33 feet you descend (go down). -
ANSWER-How does pressure increase underwater?
Pressure decreases one bar/ata for every 10 metres/33 feet you ascend (come up). -
ANSWER-How does pressure decrease underwater?
1 bar/ata - ANSWER-At 0 metres/feet (sea level), what is the total pressure?
2 bar/ata — one of air plus one of water - ANSWER-At 10 metres/33 feet, what is the
total pressure?
3 bar/ata — one of air plus two of water - ANSWER-At 20 metres/66 feet, what is the
total pressure?
4 bar/ata - ANSWER-At 30 metres/99 feet, what is the total pressure?
A gas volume decreases because the gas molecules get compressed. Gas density
increases because all the molecules are there, but they're packed into a smaller area. -
ANSWER-Pressure changes affect the volume and density of air (or any other gas). As
the pressure increases — as you go deeper — why does a gas volume decrease? Why
does gas density increase?
Your air volume decreases by 1/2, and your air density will be doubled. - ANSWER-If
you go from the surface to 10 metres/33 feet, what happens to your air volume and air
density?
Your air volume decreases by 1/3 the surface volume, and your air density will be 3
times the surface density. - ANSWER-If you go from 10 metres/33 feet to 20 metres/66
feet, what happens to your air volume and air density?
Your air volume decreases by 1/4 the surface volume, and your air density will be 4
times the surface density. - ANSWER-If you go from 20 metres/66 feet to 30 metres/99
feet, what happens to your air volume and air density?
