PADI Open Water Diver Final Exam with
Correct Answers 2025 /2026
/. 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
