deep as - ANSWER: 18 metres/60 feet
As you descend in water, the pressure - ANSWER: increases
A depth change of 10 metres/33 feet causes a pressure change of - ANSWER: 1
bar/ata (atmosphere)

ANSWER: 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 - ANSWER: burst
A squeeze is caused by - ANSWER: a pressure imbalance between the surrounding
pressure and an air space
Equalization is the process of - ANSWER: adding air to an air space
The most important rule in scuba diving is to - ANSWER: breathe continuously and
never hold your breath
During ascent I feel discomfort in my ears. I should - ANSWER: 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

your body and some of your equipment, with a mechanism for dropping some or all
the weight in an emergency

LPI mechanism - ANSWER: inflates the BCD with air from my scuba cylinder
Burst disk - ANSWER: a safety device that relieves accidental overpressure by
releasing air before reaching the pressure at which the cylinder would fail
