PADI Open Water Diver Final Exam
1. As a newly certified PADI Open Water Diver, I will be trained to dive
with buddy as deep as: 18 metres/60 feet
2. As you descend in water, the pressure: increases
3. A depth change of 10 metres/33 feet causes a pressure change of: 1
bar/ata (atmosphere)
4. if you take 6 liters of air from the surface to 20 metres/66 feet, the volume
will be: 2 litres (the density of the air would be three times the density
at the surface)
5. A balloon fully inflated and sealed at 10 metres/33 feet, would probably
during ascent to the surface: burst
6. A squeeze is caused by: a pressure imbalance between the
surrounding pres- sure and an air space
7. Equalization is the process of: adding air to an air space
1/6
,8. The most important rule in scuba diving is to: breathe continuously and
never hold your breath
9. During ascent I feel discomfort in my ears. I should: stop, descend
slightly, and allow trapped air to work its way out
10. My buddy and I descend to 12 metres/40 feet. I would expect to use my
air
at 6 metres/20 feet: faster than
11. The most efficient way to breathe dense air underwater is to breathe: -
deeply and slowly
12.Buoyancy: a force that pushes an object in water upward
13.Salt water causes more buoyancy than fresh water because it is
dense and weighs : more
14.When I descend, my buoyancy tends to . When I ascend, it
tends to : decrease, increase
15.The three most important considerations in choosing scuba equipment
2/6
, are suitability, fit, and: comfort
16.The two basic fin styles are fins: adjustable and full-foot
17.My primary considerations when choosing fins are fit and: blade size
18.BCD (buoyancy control device): holds your kit together and allows
you to adjust buoyancy throughout the dive
19.Regulator: delivers breathing air at the surrounding pressure when
you inhale and directs exhaled air into the air
20.Cylinder: holds the high-pressure breathing air supplied by your
regulator dur- ing the dive
21.Weight System: 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
