How does Boyle’s law relate to diving?
Boyle’s Law: For a fixed mass of gas at constant temperature, pressure and volume are inversely related. … As a diver descends, increase in pressure results in a decrease in gas volume (compression). Conversely, as the diver ascends compressed gas expands.
What happens if you fart while scuba diving?
Farting is possible while scuba diving but not advisable because: Diving wetsuits are very expensive and the explosive force of an underwater fart will rip a hole in your wetsuit. An underwater fart will shoot you up to the surface like a missile which can cause decompression sickness.
How does Charles law apply to diving?
Charles’ Law is often used to explain why the pressure in a scuba tank goes up when the temperature increases. But Charles’ Law states that the volume of a gas is directly proportional to its temperature. The volume of a scuba tank is constant. … The pressure of a gas is directly proportional to its temperature.
What would happen to a diver who does not exhale while surfacing from a 30 m dive?
What would happen to a diver who does not exhale while surfacing from a 30m dive? If divers must make emergency ascents from this depth they must remember to breathe out regularly as they return to the surface. If they don’t, the pressure of the air in their lungs will cause their lungs to expand.
Should scuba tanks be filled with 100 oxygen?
On the surface, pure oxygen is recommended first aid for the majority of diving injuries. A recreational diver is likely to run across pure oxygen on a dive boat at some point in his diving career.
What is oxygen toxicity in scuba diving?
Oxygen toxicity is a concern for underwater divers, those on high concentrations of supplemental oxygen (particularly premature babies), and those undergoing hyperbaric oxygen therapy. … The result of breathing increased partial pressures of oxygen is hyperoxia, an excess of oxygen in body tissues.
Why do scuba divers use nitrogen?
When you scuba dive, the longer you stay under the water (bottom time), the more nitrogen your body absorbs. If divers absorb too much nitrogen in their blood stream, they develop a condition known as “the bends” (also known as decompression sickness). … This is common and part of the diving experience.
