PADI Open Water Diver Final Exam Questions With Detailed
Answers.
As a newly certified PADI Open Water Diver, I will be trained to dive with
buddy as deep as - accurate answers-18 metres/60 feet
As you descend in water, the pressure - accurate answers-increases
A depth change of 10 metres/33 feet causes a pressure change of - accurate
answers-1 bar/ata (atmosphere)
if you take 6 liters of air from the surface to 20 metres/66 feet, the volume
will be - accurate answers-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 - accurate answers-burst
A squeeze is caused by - accurate answers-a pressure imbalance between the
surrounding pressure and an air space
Equalization is the process of - accurate answers-adding air to an air space
The most important rule in scuba diving is to - accurate answers-breathe
continuously and never hold your breath
During ascent I feel discomfort in my ears. I should - accurate answers-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 - accurate answers-faster than
The most efficient way to breathe dense air underwater is to breathe -
accurate answers-deeply and slowly
Buoyancy - accurate answers-a force that pushes an object in water upward
Salt water causes more buoyancy than fresh water because it is _____ dense
and weighs _____ - accurate answers-more
, When I descend, my buoyancy tends to ________. When I ascend, it tends to
_______ - accurate answers-decrease, increase
The three most important considerations in choosing scuba equipment are
suitability, fit, and - accurate answers-comfort
The two basic fin styles are __________ fins - accurate answers-adjustable and
full-foot
My primary considerations when choosing fins are fit and - accurate answers-
blade size
BCD (buoyancy control device) - accurate answers-holds your kit together and
allows you to adjust buoyancy throughout the dive
Regulator - accurate answers-delivers breathing air at the surrounding
pressure when you inhale and directs exhaled air into the air
Cylinder - accurate answers-holds the high-pressure breathing air supplied by
your regulator during the dive
Weight System - accurate answers-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 - accurate answers-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 - accurate answers-inflates the BCD with air from my scuba
cylinder
Burst disk - accurate answers-a safety device that relieves accidental
overpressure by releasing air before reaching the pressure at which the
cylinder would fail
