As a newly certified PADI Open Water Diver, I will be trained to dive with buddy as deep as - correct answers.18 metres/60 feet As you descend in water, the pressure - correct ases A depth change of 10 metres/33 feet causes a pressure change of - correct answers.1 bar/ata (atmosphere) if you take 6 liters of air from the surface to 20 metres/66 feet, the volume will be - correct answers.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 - correct A squeeze is caused by - correct answers.a pressure imbalance between the surrounding pressure and an air space Equalization is the process of - correct g air to an air space The most important rule in scuba diving is to - correct he continuously and never hold your breath During ascent I feel discomfort in my ears. I should - correct , 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 - correct r than The most efficient way to breathe dense air underwater is to breathe - correct y and slowly Buoyancy - correct answers.a force that pushes an object in water upward Salt water causes more buoyancy than fresh water because it is _____ dense and weighs _____ - correct When I descend, my buoyancy tends to ________. When I ascend, it tends to _______ - correct ase, increase The three most important considerations in choosing scuba equipment are suitability, fit, and - correct rt The two basic fin styles are __________ fins - correct table and full-foot My primary considerations when choosing fins are fit and - correct size BCD (buoyancy control device) - correct your kit together and allows you to adjust buoyancy throughout the dive Regulator - correct ers breathing air at the surrounding pressure when you inhale and directs exhaled air into the air Cylinder - correct the high-pressure breathing air supplied by your regulator during the dive Weight System - correct 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 - correct 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 - correct tes the BCD with air from my scuba cylinder Burst disk - correct answers.a safety device that relieves accidental overpressure by releasing air before reaching the pressure at which the cylinder would fail
