as you descend. - ANSWER ✅✅✅✅add air to your buoyancy device.
A depth that is equivalent to one atmosphere in the ocean is equivalent to _____ in sea
water and _____ in fresh water. - ANSWER ✅✅✅✅10m (33ft) ; 10.4m (34ft)
The minimum surface interval to avoid decompression after a dive to 88ft for 18
minutes, followed by a dive to 78ft for 23 minutes is... - ANSWER ✅✅✅✅4hr and
49minutes
Diving equipment should be: - ANSWER ✅✅✅✅rinsed thoroughly, dried and stored in
a cool place.
To relieve a cramp in the calf: - ANSWER ✅✅✅✅Bend the toe of the fin toward the

According to the NAUI dive tables, dives to less than 6m (20ft): - ANSWER ✅✅✅✅Are
considered as 6m (20 foot) dives.
Which gas law best explains diving medical problems such as ear and sinus squeeze? -
ANSWER ✅✅✅✅Boyles law
Explain Boyles Law: - ANSWER ✅✅✅✅- Suppose we had a balloon measuring one
cubic foot at the surface of the water. This balloon is under 1 ATM (14.7psi) of pressure.
- If we push the balloon underwater and take it to a depth of 33 feet, it is now under 2
ATM of pressure (29.4lb) - 1 atm of pressure from the air plus 1 ATM of pressure from
the water.
- Boyle's Law then tells us that since we have twice the absolute pressure, the volume
of the balloon will be decreased to one half.
- It follow then, that taking the balloon to 66 feet, the pressure would compress the
balloon to one third its original size, 99 feet would make it 1/4 etc.
Which of the following will help prevent seasickness? - ANSWER ✅✅✅✅Settle
yourself at a midway point of the boat.
You should have your regulator serviced by a certified repair technician: - ANSWER

✅✅✅✅The tide

ANSWER ✅✅✅✅60 minutes.
In the ocean a sealed balloon filled with air that has a volume of 98 cubic centimeters (6
cubic inches) at 30 meters (99 feet) will have a volume of _____ at 10 meters (33 feet).
- ANSWER ✅✅✅✅196 cubic centimeters (12 cubic inches)
, (99fsw-33fsw)/33fsw = 2 atm,
2atm X 6 cubic inches = 12 cubic inches of air.
What is the most effective way to descend while maintaining orientation and attempting
equalization of the ears? - ANSWER ✅✅✅✅Feet first
Weighting systems are used by the diver primarily to: - ANSWER ✅✅✅✅Offset the
