PADI OPEN WATER DIVER QUESTIONS WITH CORRECT AND COMPLETE SOLUTIONS RATED A+

as you descend in water the pressure - increases a depth change of 10 meters/33 feet causes a pressure chance of - 1 bar/ata if you take 6 liters of air from the surface to 20 meters/66feet, the volume will be - 2 litres a balloon fully inflated and sealed at 10 meters/33 feet, would probably _____ during ascent to the surface - burst as I descend, increasing pressure affects my - mask,ears, sinuses a squeeze is caused by - pressure imbalance between the surrounding pressure and an air space equalization is the process of... - adding air to an air space I should equalize... - before I feel pain or discomfort I'm descending and discovering I can't equalize. The first thing I would do is... - stop my descent and signal my buddy/the instructor I equalize gently because an extended, forceful equalization can cause permanent damage to my ears and hearing (T/F) - true On a day I plan to go diving, I wake up with my sinuses blocked due to a cold or allergy. I should... - cancel the dive until I'm well when scuba diving, normal breathing keeps your lungs equalized to the surrounding pressure (T/F) - true My buddy and I descend to 12 meters/40 feet. I would expect to use my air ______ at 6 meters/20 feet - faster than the most efficient way to breathe dense air underwater is to breathe - deeply and slowly my body responds to anxiety with increased breathing, but slow breathing helps reduce anxiety (T/F) - true which of the following are among the breathing rules I follow as a diver? a. breathe continuously and never hold my breath b. breathe slowly and deeply c. do not allow myself to get winded or out of breath d. if faced with a problem, stop them maintain or restore slow deep breathing - all of the above buoyancy is a force that pushes an object in water upward (T/F) - true MY sunglasses case falls out of my pocked into the water but fortunately, it floats so I retrieve it. The case is _____ buoyant. - positively Salt water causes more buoyancy than fresh water because it is less dense and weighs less (T/F) - false, salt water causes more buoyancy because it is more dense and weighs more to control my buoyancy, normally I will sue my weight system and my - BDC when I descend, my buoyancy tends to _____. When I ascend it tends to _____ - decrease, increase Underwater, when I inhale, by buoyancy - increases slightly It is important to master buoyancy control because it affects almost everything I do in and underwater (T/F) - true In recreational diving, the buddy system means diving with another diver or divers in a team that provides assistance and safety benefits (T/F) - true Overall benefits of the buddy system include: icality y - a,b,c the three most important considerations in choosing scuba equipment are suitability, fit, and _____ - comfort getting the service my gear needs may be a consideration when choosing equipment (T/F) - true Before each use, I should _____ my equipment - inspect I need a mask because - my eyes must be in air to focus my mask encloses my nose so I can - equalize the mask I should choose a mask that fits as far away from my face as possible (T/f) - false, choose a lot profile that sits as close as possible I want to adjust my mask so the strap rests _____ - above my ears, over the crown of my head Snorkels are standard equipment for scuba diving because they allow me to breathe with my face in the water or in rough conditions, without wasting my scuba air, especially when I have little scuba air remaining. (T/F) - true some scuba divers prefer a snorkel with a flexible lower portion so it drops out of the way when not in use (T/F) - true
