PADI Open Water Diver Final ExamQuestions and Solutions 2024
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

_______ - -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
