This means it causes more upward force (buoyancy) on an object. An object that is neutrally buoyant in fresh water would float in salt water because there is greater upward force. ,,, See Being a Diver I - Buoyancy and Controlling Buoyancy. - answers>1) If an object is neutrally buoyant (does not sink or float) in fresh water, the same object placed into salt water would A sink. B either sink or float. C do nothing. D float. B The balloon will get smaller and the air inside the balloon will be more dense (molecules move closer together). As water pressure increases, the volume of an air space will decrease. This causes the density of the air inside to increase and air molecules are pushed closer together. The balloon would get smaller and the air density inside would be greater. See Being a Diver I - Water Pressure and Air Volume Effects. - answers>2) I blow up a balloon, tie it off, and take it to the bottom of the swimming pool. What will happen to the balloon and the air inside it? A The balloon will get bigger and the air inside the balloon will be less dense (molecules move further apart).

D The balloon will get smaller and the air inside the balloon will be less dense. P a g e 2 | 26 A become half the size it was at the surface. At 10 meters, the pressure is 2 bar. An air volume taken to this depth from the surface would decrease and become half the size. See Being a Diver I - Water Pressure and Air Volume Effects. - answers>3) I turn a glass upside down, trap the air in it by putting it in water, and then I take the glass down to 10 meters. The air space would A become half the size it was at the surface. B not change in size. C become 1/3 the size it was at the surface. D become 2/3 the size it was at the surface. C A cold, allergy or another medical problem. A cold, or any congestion, can block air passages in your ears and sinuses, making equalization difficult or impossible. See Being a Diver I - The Effects of Increasing Pressure on Body Air Spaces. - answers>4) If I am not able to equalize (clear) my body air spaces, it may be because I have A seasickness. B heart disease and high blood pressure. C a cold, allergy or another medical problem. D anxiety. C I am feeling a squeeze and need to equalize. Pain in your ears or sinuses means that they aren't equalized. Stop your descent and ascend slightly to relieve pressure on your ears. Then attempt to equalize again. If you can't equalize, end the dive.

See Being a Diver II - Overexertion. - answers>16) If I work too hard and find it difficult to breathe underwater, I should A inflate my BCD. B stop all activity and rest, holding onto something for support if possible. C swim immediately to my buddy and signal for help. D do a controlled emergency swimming ascent (CESA - swimming up to the surface saying the ah-h-h-h sound). A Compress (feel thinner) from water pressure, and I will lose buoyancy and warmth. The small bubbles in your wet suit compress as you get deeper. This causes your buoyancy to decrease and makes the wet suit thinner, which affects warmth. To control your buoyancy, add small amounts of air to your BCD frequently during descent. See Being a Diver II - Descents in Open Water. - answers>17) As I descend (go down), my wet suit will A compress (feel thinner) from water pressure, and I will lose buoyancy and warmth.
