![]() ![]() The absolute pressure at 20 metres / 66 feet of salt water is:ĭ. The answer cannot be determined be determined from the information given.ĭ. ASK BROOKE If an object is neutrally buoyant in fresh water, what will happen to the object when it's placed in salt water?Ī. ![]() the surrounding pressure is greater, thus exposure to higher pressure may increase bubble formation. pressure gradient and many increase bubble formation.ĭ. dive tables and computers are based on surfacing at sea level, thus exposure to lower pressure increases the tissue. the partial pressure of inhaled oxygen is greater than the partial pressure of nitrogen in the tissues.Ĭ. altitude sickness can contribute to the formation of nitrogen bubbles in the blood stream.ī. 0.15 Scuba divers who ascend to altitude soon after completing a dive increase their risk of decompression sickness because:Ī. 05% carbon monoxide at a pressure of three atmospheres, it will have the same physical effect as if the diver were breathing _% carbon monoxide at one atmosphere.ĭ. 5 liters If a diver breathes from a cylinder that contains. Four times a dense If a balloon is filled to 1 litre at 40 metres/ 132 feet and then released, assuming it does not explode, what will its volume be upon reaching the surface?ĭ. Approximately how much denser is the air you breathe at depth of 30 metres/ 99 feet as compared to the surface?ĭ.
