PADI OPEN WATER DRIVER FINAL EXAM 2024 NEWEST
2 VERSIONS (VERSION A AND B) COMPLETE 250
QUESTIONS WITH DETAILED VERIFIED
ANSWERS/ALREADY GRADED A+
1: If an object is neutrally buoyant (does not sink or float) in fresh water, the same
object placed into salt water would
A sink.
B either sink or float.
C do nothing.
D float. - ANSWER: D Float.
Salt water is heavier than fresh water because it has dissolved minerals in it. This
means it causes more upward force (buoyancy) on an object. An object that is
neutrally buoyant in fresh water would float in salt water because there is greater
upward force. See Being a Diver I - Buoyancy and Controlling Buoyancy.
2: I blow up a balloon, tie it off, and take it to the bottom of the swimming pool.
What will happen to the balloon and the air inside it?
A The balloon will get bigger and the air inside the balloon will be less dense
(molecules move further apart).
B The balloon will get smaller and the air inside the balloon will be more dense
(molecules move closer together).
C The balloon will get bigger and the air inside the balloon will be more dense.
D The balloon will get smaller and the air inside the balloon will be less dense. -
ANSWER: B The balloon will get smaller and the air inside the balloon will be more
dense (molecules move closer together).
As water pressure increases, the volume of an air space will decrease. This causes
the density of the air inside to increase and air molecules are pushed closer together.
The balloon would get smaller and the air density inside would be greater. See Being
a Diver I - Water Pressure and Air Volume Effects.
3: I turn a glass upside down, trap the air in it by putting it in water, and then I take
the glass down to 10 metres/33 feet. The air space would
A become half the size it was at the surface.
B not change in size.
C become 1/3 the size it was at the surface.
D become 2/3 the size it was at the surface. - ANSWER: A Become half the size it was
at the surface.
,At 10 metres/33 feet, the pressure is 2 bar/ata. An air volume taken to this depth
from the surface would decrease and become half the size. See Being a Diver I -
Water Pressure and Air Volume Effects.
4: If I am not able to equalize (clear) my body air spaces, it may be because I have
A seasickness.
B heart disease and high blood pressure.
C a cold, allergy or another medical problem.
D anxiety. - ANSWER: C A cold, allergy or another medical problem.
A cold, or any congestion, can block air passages in your ears and sinuses, making
equalization difficult or impossible. See Being a Diver I - The Effects of Increasing
Pressure on Body Air Spaces.
5: If my ears or sinuses hurt while I am descending (going down), it usually means
A my air spaces are equalized.
B my mask strap is too tight.
C I am feeling a squeeze and need to equalize.
D my mask is too small. - ANSWER: C I am feeling a squeeze and need to equalize.
Pain in your ears or sinuses means that they aren't equalized. Stop your descent and
ascend slightly to relieve pressure on your ears. Then attempt to equalize again. If
you can't equalize, end the dive. See Being a Diver I - The Effects of Increasing
Pressure on Body Air Spaces.
6: The best place for me to position an alternate air source is
A loose by my side so I can find it fast.
B in the triangle area formed by my chin and the lower corners of my rib cage.
C to the base of my cylinder.
D to the back of my BCD between my shoulder blades and waist. - ANSWER: B In the
triangle area formed by my chin and the lower corners of my rib cage.
Your alternate air source attaches with a quick release in the triangle area formed by
your chin and the lower corners of your rib cage. Avoid letting your alternate air
source dangle unsecured from your kit. See Equipment I - Regulators.
7: Lung overexpansion injuries can be caused by
A scuba diving without a buddy.
B continuing a dive when not properly weighted.
C not drinking enough water before scuba diving.
D holding my breath while scuba diving. - ANSWER: D Holding my breath while scuba
diving.
, Blocking off your lungs by holding your breath and ascending could cause them to
overexpand and rupture, which is a serious injury that could result in paralysis and
death. Breathing continuously while scuba diving keeps air passages open allowing
expanding air to escape. See Being a Diver I - The Effects of Decreasing Pressure on
Body Air Spaces.
8: If my cylinder of air lasts 60 minutes while I am at the surface breathing normally,
assuming all else is the same, how long will it last at 20 metres/66 feet breathing
normally?
A 60 minutes
B 20 minutes
C 15 minutes
D 12 minutes - ANSWER: B 20 minutes
9: How often should I take my scuba cylinder to be visually inspected by my dive
center?
A Once a year.
B Once every two years.
C Every six months.
D Every five years. - ANSWER: A Once a year.
Have your cylinder visually inspected annually for internal corrosion or other
contamination/damage. See Equipment I - Cylinders.
10: The difference between DIN valves and yoke valves is that DIN valves
A are made from durable plastic.
B contain a spring-operated shutoff valve that is held open by cylinder pressure.
C have an o-ring in them.
D have threaded openings to screw the regulator into. - ANSWER: D Have threaded
openings to screw the regulator into.
With the DIN system, the regulator screws into the valve. The yoke system holds the
regulator first stage to the cylinder with a clamp system. See Equipment I - Cylinders.
11: Which of the following is part of proper care for my scuba cylinder?
A Sand and repaint it every year.
B Dry it in the sun.
C Keep some air in it.
D Have it pressure tested every month. - ANSWER: C Keep some air in it.
You should keep some air in the cylinder to prevent moisture from entering and
causing corrosion. Also have it pressure tested at required intervals, usually two to
