PADI Scuba - Open Water Exam Questions With Detailed
Solutions.
Padi's Four E Philosophy - accurate answers-Equipment, Education,
Experience, Environment
0-1 As a newly certified PADI Open Water Diver, I will be trained to dive with
a buddy as deep as _____ - accurate answers-18 meters/60 feet
1-1.1 As you descend, what happens to pressure - accurate answers-Increases
How does pressure increase as you descend? - accurate answers-The pressure
increases by one bar/ata for each 10 meters/33 feet you descend
What is the pressure at 0 meters/0 feet? - accurate answers-1 bar/ata
What happens to air volume as depth and pressure increase? - accurate
answers-Volume decreases, for example if you are at the depth of 33 ft,
pressure would be 2 bar/ata and air volume would be 1/2
What happens to air density as depth and pressure increase? - accurate
answers-Air Density increases, for example if you are at the depth of 33 ft,
pressure would be 2 bar/ata and air density would be x2
1-1.5 A balloon fully inflated and sealed at 10 meters/33 feet would probably
____ during ascent to the surface - accurate answers-Burst
1-2.1 As I descend, increasing pressure affects my: - accurate answers-mask,
ears, sinuses
A squeeze is caused by: - accurate answers-a pressure imbalance between the
surrounding pressure and an air space
1-2.3 Equalization is the process of: - accurate answers-Adding air to an air
space
1-2.4 I should equalize: - accurate answers-Before I feel pain or discomfort
, 1-2.5 I'm descending and I discover I can't equalize. The first think I would do
is: - accurate answers-stop by descent and signal my buddy/the instructor
1-3.1 The most important rule in scuba diving is to: - accurate answers-
Breathe continuously and never hold your breath
Holding your breath while scuba diving can lead to: - accurate answers-lung
overexpansion injuries
1-3.3 During ascent I feel discomfort in my ears. I should: - accurate answers-
stop, descend slightly and allow trapped air to work its way out
Positive buoyancy - accurate answers-floats
negative buyoancy - accurate answers-sinks
neutral buoyancy - accurate answers-weighs the same as the water it
displaces and neither floats nor sinks
When I descend, my buoyancy tends to: - accurate answers-decrease
When I ascend, my buoyancy tends to: - accurate answers-increase
What are the three most important considerations in choosing scuba
equipment? - accurate answers-suitability, fit, and comfort
What are the two basic fin styles? - accurate answers-adjustable and full-foot
My primary considerations while choosing fins are: - accurate answers-fit and
blade size
Burst disk - accurate answers-a safety device that relieves accidental
overpressure by releasing air before reaching the pressure at which the
cylinder would fail
How often do scuba cylinders require pressure testing? - accurate answers-
Every 2-5 years
