Why do the bubbles exhaled by a scuba diver grow as they aproach the surface of the ocean?

as the bubbles get closer to the surface, there is less water pressure on them therefore allowing them to expand.

∙ 15y agoThis is because of Boyle's law, which means that the air becomes less pressurized by the density of the water, and so they grow.

Explain the advantages of being neutrally buoyant when you are a scuba diver.?
You do not float to the surface nor do you sink- you stay at the level you swim to.
What part of a diver's body might be hurt during a deep dive and why is this so?
During the deep dive the divers body goes through immense pressure. The atmospheric pressure in the deep as one goes more deep it increases so the lungs of the diver has to do more work and also that if the diver comes up on surface faster ten the rate he went down then the helim would be formed in the lungs of diver which can be lethal.
After the diver jumps forward from the diving board the force of gravity will accelerate the diver parallel to the direction of motion?
No. It will accelerate the diver downward only.
Who will hear the sound of an approaching boat first this diver or his friend above the water?
The diver
Will a sky diver with a greater mass accelerate faster that a sky diver with less mass?
Yes
When a scuba diver dives into water why are the gas bubbles they release always spherical?
The gas bubbles exhaled by a SCUBA diver are always spherical for two reasons: the gas molecules are pushing outward from the bubble in all directions with the same amount of force. In addition, the water outside the gas bubble is squeezing the bubble inward in all directions with the same amount of force.
Why do the air bubbles of a diver head toward the surface?
Becuase air is less dense than water so it raises above it
Why it is dangerous for scuba diver to more up rapidly into the water surface?
A scuba diver should not ascend rapidly, because the nitrogen in their bloodstream will lose pressure and create bubbles in the bloodstream. This will cause decompression sickness, which can be fatal.
Why is it important for a deep sea diver to resurface at a gradual rate?
because bubbles of nitrogen that are abosrbed into the blood at high pressures but are normally insoluble start being released from the blood as the diver rises. If this happens to quickly bubbles in the blood form and the diver gets the bends
The stunt diver used an oxygen tank until he reached the surface?

How do nitrogen reach man?
Nitrogen enters the bloodstream in the form of miniscule bubbles.. The effect of nitrogen is most visible in S.C.U.B.A. diving. whereas for example at a depth of 30 meters, 4 times as much air enters your lungs, and 4 times as much nitrogen. And when the diver goes back up to the surface, all those bubbles start to expand due to the decreasing pressure.. and if the diver isn't careful by going up slowly, and stopping at some points, in order to evacuate excess nitrogen by exhalation, the blood 'boils' and the diver has a decompression accident.. where an accumulation of bubbles can get stuck in an artery, or in the heart, etc..
What do they call it when a scuba diver comes to surface to quick?
they get the bends
What is the reason for DCS?
If the diver surfaces too quickly, however, potentially dangerous nitrogen bubbles can form in the tissues and cause DCS. These bubbles can compress nerves, obstruct arteries, veins,
What is the complet subject in the sentence the stunt driver used an oxygen tank until he reached the surface?

Why do scuba divers form air bubbles in their blood stream?
When diving, scuba divers breathe gas under pressure. The greater pressure causes the nitrogen in the breathing gas to dissolve in their bodily tissues (the body metabolises the oxygen). When the diver ascends from depth, the pressure is reduced, and so the gas comes out of the tissues and into the bloodstream, where the diver expels it through his lungs. Normally these bubbles are very small (sometimes called "micro" bubbles or "silent" bubbles) and present no risk to the diver. Normal off-gassing in this was is not harmful, but if a diver stays too deep for too long, the rapid release of gas can form larger bubbles which can cause decompression sickness. In minor cases this can cause discomfort and localised swelling, which can normally be resolved with oxygen. Severe cases can lead to permanent tissue damage, paralysis and even death. This is why divers are trained to understand no-decompression limits and to utilise tables or dive computers to keep them safely within margins.
What are two types of diver flags?
There are two types of diver down flags - the diver down flag and the alpha flag. The red diver down flag is used when divers are in the water to alert boats to the possibility of divers near the surface, and the blue alpha flag is flown by a boat whenever the mobility of the vessel is restricted.
