Exam!!||, 2026/2027-Question Entry-Level Scuba
Certification Examination||Newest Exam!!!
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
,2|Page
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
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)
,3|Page
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
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
, 4|Page
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
