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