SCUBA

a depth change of 10 metres/33 feet causes a pressure change of

2 bar/ata

if you take 6 liters of air from the surface to 20 metres/66 feet, the volume will be

2 litres

T or F: I equalize gently because an extended, forceful equalization can cause permanent damage to my ears and hearing

True

T or F: My body responds to anxiety with increased breathing, but slow breathing helps reduce anxiety

True

buoyancy is

a force that pushes an object in water upward

equalization is the process of

adding air to an air space

the most important rule in scuba diving is to

breath continuously and never hold your breath

a balloon fully inflated and sealed at 10 metres/33 feet, would probably ____ during ascent to the surface

burst

the most efficient way to breathe dense air underwater is to breathe

deeply and slowly

As I descend, increasing pressure affects my

mask

to control my buoyancy, normally I will use my weight system and

my BCD

I'm descending and I can't equalize. The first thing I would do is

stop my descent, signal my buddy/instructor
