PADI Open Water Diver Final Exam with 100% Correct
Answers 2024 /2025
As a newly certified PADI Open Water Diver, I will be trained to dive with buddy as deep as -
-18 metres/60 feet
As you descend in water, the pressure - -increases
A depth change of 10 metres/33 feet causes a pressure change of - -1 bar/ata
(atmosphere)
if you take 6 liters of air from the surface to 20 metres/66 feet, the volume will be - -2
litres (the density of the air would be three times the density at the surface)
A balloon fully inflated and sealed at 10 metres/33 feet, would probably ______ during
ascent to the surface - -burst
A squeeze is caused by - -a pressure imbalance between the surrounding pressure
and an air space
Equalization is the process of - -adding air to an air space
The most important rule in scuba diving is to - -breathe continuously and never hold
your breath
During ascent I feel discomfort in my ears. I should - -stop, descend slightly, and
allow trapped air to work its way out
My buddy and I descend to 12 metres/40 feet. I would expect to use my air _____ at 6
metres/20 feet - -faster than
The most efficient way to breathe dense air underwater is to breathe - -deeply and
slowly
Buoyancy - -a force that pushes an object in water upward
Salt water causes more buoyancy than fresh water because it is _____ dense and weighs
_____ - -more
When I descend, my buoyancy tends to ________. When I ascend, it tends to _______ -
-decrease, increase
The three most important considerations in choosing scuba equipment are suitability, fit,
and - -comfort
The two basic fin styles are __________ fins - -adjustable and full-foot
My primary considerations when choosing fins are fit and - -blade size

BCD (buoyancy control device) - -holds your kit together and allows you to adjust
buoyancy throughout the dive
Regulator - -delivers breathing air at the surrounding pressure when you inhale and
directs exhaled air into the air
Cylinder - -holds the high-pressure breathing air supplied by your regulator during
the dive
Weight System - -holds lead weight to counteract the positive buoyancy of your body
and some of your equipment, with a mechanism for dropping some or all the weight in an
emergency
The five components that make up a BCD include - -an inflatable bladder, a cylinder
band and harness/jacket, an LPI (low-pressure inflator) mechanism, an overpressure/quick
exhaust valves, and a weight system
LPI mechanism - -inflates the BCD with air from my scuba cylinder
Burst disk - -a safety device that relieves accidental overpressure by releasing air
before reaching the pressure at which the cylinder would fail
scuba cylinders require pressure testing _______ and visual inspection _________ - -
every 2-5 years, annually
The most important feature in my weight system is its - -quick release
Trim means having the right _____ of weight - -distribution
Failure to follow the most important rule in scuba diving can cause serious lung
overexpansion injuries, which in turn can cause paralysis and death - -true
An object that is neutrally bouyant in fresh water will _____ in salt water - -float
Underwater objects appear - -larger and/or closer
Sound travels about 4 times _____ in water than in air, making it difficult to determine its
source - -faster
To move efficiently as a diver, I should move - -slowly and steadily
Trim is important for streamlining because - -poor trim raises or lowers my feet,
causing drag
Overexertion results from - -a prolonged increased effort
