Answers 2024 /2025
What is buoyancy? - ✔✔ANSW✔✔..Buoyancy is an upward force produced from a
liquid pushing on an object.
My sunglasses case falls out of my pocket into the water, but fortunately, it floats so I
retrieve it. I would say my sungalsses case is [blank] buoyant. -
✔✔ANSW✔✔..Positively
Salt water causes more buoyancy than fresh water because it is less dense and weighs
less. True or false? - ✔✔ANSW✔✔..False. Salt water causes more buoyancy because it
is more dense and weighs more; buoyancy results from the weight of the water
displaced.
To control my buoyancy, normally I will use my weight system and my [blank] -
✔✔ANSW✔✔..BCD
When I descend, my buoyancy tends to [blank]. When I ascend, it tends to [blank]. -
✔✔ANSW✔✔..decrease, increase
Underwater, when I inhale, my buoyancy [blank] - ✔✔ANSW✔✔..increases slightly
It is important to master buoyancy control because it affects almost everything I do in
and underwater. True or false? - ✔✔ANSW✔✔..True
As you descend in water the pressure increases, decreases or doesn't change? -
✔✔ANSW✔✔..increases
A depth change of 10 meters/33 feet causes a pressure change of 1, 2, 3, or 4 bar/ata?
- ✔✔ANSW✔✔..1 bar/ata
If you take 6 litres of air from the surface to 20 metres/66 feet, the volume will be [blank]
litres. 1,2,3,4 - ✔✔ANSW✔✔..2
The density of 6 liters of air at 20 metres/66 feet would be [blank] the density at the
surface - ✔✔ANSW✔✔..3 times
, A balloon fully inflated and sealed at 10 metres/33 feet, would probably [blank] during
ascent to the surface. - ✔✔ANSW✔✔..burst
As I descend, increasing pressure affects my - choose all that apply - mask, ears,
sinuses, skin - ✔✔ANSW✔✔..mask, ears, sinuses
A squeeze is caused by - ✔✔ANSW✔✔..a pressure imbalance between the
surrounding pressure and an air space
Equalization is the process of - ✔✔ANSW✔✔..adding air to an air space
When should I equalize? - ✔✔ANSW✔✔..before I feel pain or discomfort
I'm descending and discover I can't equalize. The first thing I would do is -

I should - ✔✔ANSW✔✔..cancel the dive until I am well
When scuba diving, normal breathing keeps your lungs equalized to the surrounding
pressure - ✔✔ANSW✔✔..True
The most important rule in scuba diving is to - ✔✔ANSW✔✔..breathe continuously and
never hold your breath
Failure to follow the most important rule in scuba diving can cause severe lung over-
expansion injuries, which can result in paralysis or death - ✔✔ANSW✔✔..True
During ascent I feel discomfort in my ears. I should - ✔✔ANSW✔✔..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 [blank] at 6
metres/20 feet. slower than, faster than, at the same rate as... - ✔✔ANSW✔✔..faster
than
The most efficient way to breathe dense air underwater is to breathe -
✔✔ANSW✔✔..deeply and slowly
My body responds to anxiety with increased breathing, but slow breathing helps reduce
anxiety. True or false? - ✔✔ANSW✔✔..True
