PADI Open Water Diver Final Exam
As a newly licensed PADI Open Water Diver, I could be trained to dive with pal as deep as -
ANS18 metres/60 toes
As you descend in water, the pressure - ANSincreases
A depth trade of 10 metres/33 feet causes a stress alternate of - ANS1 bar/ata (ecosystem)
if you take 6 liters of air from the surface to twenty metres/sixty six feet, the volume can be -
ANS2 litres (the density of the air could be 3 instances the density at the floor)
A balloon fully inflated and sealed at 10 metres/33 ft, could probably ______ all through ascent
to the floor - ANSburst
A squeeze is as a result of - ANSa strain imbalance between the encompassing strain and an
air area
Equalization is the technique of - ANSadding air to an air area
The maximum vital rule in scuba diving is to - ANSbreathe constantly and in no way preserve
your breath
During ascent I sense pain in my ears. I ought to - ANSstop, descend barely, and permit trapped
air to work its way out
My pal and I descend to 12 metres/forty toes. I would count on to use my air _____ at 6
metres/20 toes - ANSfaster than
The most efficient way to breathe dense air underwater is to breathe - ANSdeeply and slowly
Buoyancy - ANSa pressure that pushes an object in water upward
Salt water causes greater buoyancy than fresh water because it is _____ dense and weighs
_____ - ANSmore
When I descend, my buoyancy has a tendency to ________. When I ascend, it tends to
_______ - ANSdecrease, increase
The three most important considerations in choosing scuba gadget are suitability, fit, and -
ANScomfort
, The simple fin styles are __________ fins - ANSadjustable and full-foot
My number one concerns while selecting fins are in shape and - ANSblade size
BCD (buoyancy control tool) - ANSholds your package collectively and lets in you to regulate
buoyancy at some stage in the dive
Regulator - ANSdelivers breathing air at the encompassing stress when you inhale and directs
exhaled air into the air
Cylinder - ANSholds the high-stress respiratory air furnished with the aid of your regulator during
the dive
Weight System - ANSholds lead weight to counteract the superb buoyancy of your frame and a
number of your gadget, with a mechanism for losing a few or all the weight in an emergency
The five components that make up a BCD encompass - ANSan inflatable bladder, a cylinder
band and harness/jacket, an LPI (low-strain inflator) mechanism, an overpressure/brief exhaust
valves, and a weight machine
LPI mechanism - ANSinflates the BCD with air from my scuba cylinder
Burst disk - ANSa safety device that relieves unintended overpressure via releasing air earlier
than attaining the stress at which the cylinder would fail
scuba cylinders require pressure trying out _______ and visual inspection _________ -
ANSevery 2-five years, annually
The most important function in my weight device is its - ANSquick launch
Trim way having the proper _____ of weight - ANSdistribution
Failure to follow the maximum vital rule in scuba diving can reason extreme lung overexpansion
injuries, which in turn can motive paralysis and demise - ANStrue
An object that is neutrally bouyant in fresh water will _____ in salt water - ANSfloat
Underwater items seem - ANSlarger and/or closer
Sound travels approximately four instances _____ in water than in air, making it tough to decide
its supply - ANSfaster
To circulate correctly as a diver, I must pass - ANSslowly and steadily
