PADI Open Water Diver Final Exam 2023-
2024 Questions and Answers. (Already
Graded A+)
As a newly certified PADI Open Water Diver, I will be trained to dive with buddy as deep
as - ANSWER-18 metres/60 feet
As you descend in water, the pressure - ANSWER-increases
A depth change of 10 metres/33 feet causes a pressure change of - ANSWER-1 bar/ata
(atmosphere)
if you take 6 liters of air from the surface to 20 metres/66 feet, the volume will be -
ANSWER-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 - ANSWER-burst
A squeeze is caused by - ANSWER-a pressure imbalance between the surrounding
pressure and an air space
Equalization is the process of - ANSWER-adding air to an air space
The most important rule in scuba diving is to - ANSWER-breathe continuously and
never hold your breath
During ascent I feel discomfort in my ears. I should - ANSWER-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 - ANSWER-faster than
The most efficient way to breathe dense air underwater is to breathe - ANSWER-deeply
and slowly
Buoyancy - ANSWER-a force that pushes an object in water upward
Salt water causes more buoyancy than fresh water because it is _____ dense and
weighs _____ - ANSWER-more
, When I descend, my buoyancy tends to ________. When I ascend, it tends to _______
- ANSWER-decrease, increase
The three most important considerations in choosing scuba equipment are suitability, fit,
and - ANSWER-comfort
The two basic fin styles are __________ fins - ANSWER-adjustable and full-foot
My primary considerations when choosing fins are fit and - ANSWER-blade size
BCD (buoyancy control device) - ANSWER-holds your kit together and allows you to
adjust buoyancy throughout the dive
Regulator - ANSWER-delivers breathing air at the surrounding pressure when you
inhale and directs exhaled air into the air
Cylinder - ANSWER-holds the high-pressure breathing air supplied by your regulator
during the dive
Weight System - ANSWER-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 - ANSWER-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 - ANSWER-inflates the BCD with air from my scuba cylinder
Burst disk - ANSWER-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 _________ -
ANSWER-every 2-5 years, annually
The most important feature in my weight system is its - ANSWER-quick release
Trim means having the right _____ of weight - ANSWER-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 - ANSWER-true
An object that is neutrally bouyant in fresh water will _____ in salt water - ANSWER-
float
Underwater objects appear - ANSWER-larger and/or closer
