metres/60 feet

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

increase



The three most important considerations in choosing scuba equipment are suitability, fit, and -Ans-
comfort

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



LPI mechanism -Ans-inflates the BCD with air from my scuba cylinder



Burst disk -Ans-a safety device that relieves accidental overpressure by releasing air before reaching the
pressure at which the cylinder would fail
