As a newly certified PADI Open Water Diver, I will be trained to dive with
buddy as deep as - -18 metres/60 feet

bar/ata (atmosphere)
✅✅
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)
✅✅
A balloon fully inflated and sealed at 10 metres/33 feet, would probably
______ during ascent to the surface - -burst
A squeeze is caused by - ✅✅ -a pressure imbalance between the
surrounding pressure and an air space
✅✅-adding air to an air space
Equalization is the process of -
The most important rule in scuba diving is to - ✅✅-breathe continuously and
never hold your breath
During ascent I feel discomfort in my ears. I should - ✅✅-stop, descend
slightly, and allow trapped air to work its way out

inhale and directs exhaled air into the air
Cylinder -✅✅ -holds the high-pressure breathing air supplied by your

bladder, a cylinder band and harness/jacket, an LPI (low-pressure inflator)
mechanism, an overpressure/quick exhaust valves, and a weight system
LPI mechanism - ✅✅-inflates the BCD with air from my scuba cylinder
