Imagine filling a balloon with 1 litre of air at the surface of the ocean (1 atmosphere of pressure).
- At 10msw (metres of saltwater) of depth the pressure is double that of the surface (2atm) and the volume of the balloon will be halved.
- The actual amount of air has not halved just the space it takes up.
- The density of the air at 10m is two times the density of the air at the surface.
- If we go to 20msw the pressure is 3atm and the volume will be 1/3 of the surface volume and the air will be 3 times as dense etc ....
Now imagine the opposite.
- We Fill a balloon at 10msw with 1 litre of the air that is 2 times as dense.
- We take this balloon to the surface.
- The air in the balloon will have expanded to double the starting volume as the pressure halved (2atm to 1atm) and the density will be half what it was at the start.
Balloons have a reasonable capacity for expanding .... lungs don't. So if a Scuba diver takes a breath of air at depth and then ascends the air will expand and, if the diver is not breathing out, will cause damage and possibly bursting of the lungs.

How do you look after your lungs?
Try not to smoke, breathe regulary and if you have asthma don't go scuba diving.
What happens to a man's lungs scuba diving at 30 ft?
The scuba regulator is supposed to keep the lungs at normal size; but you only have to move half as much "air" to move the same number of molecules.
What makes your lungs rupture while scuba diving?
Lungs can rupture due to a buildup of pressure and the ost common cause of this is holding your breath when ascending. Due to Boyle's law, as the pressure decreases when you ascend, the volume increases. And if you do not exhale, the lungs will increase in volum to a point where one might rupture.
Would free diving with a Spare Air system be affective and worth it?
No and no, the law of expanding gases may cause death or damage to your lungs. If you take a breath from a spare air tank at depth and you ascend the compressed air will expand and may kill you. If diving with ANY breathing apparatus you must get certified in scuba...learn basic laws of diving, live longer
What is left inside the tank if you are scuba diving and use up all the air?
There will be air left in the tank. But it is not under enough pressure to come out of the bottle and into your lungs. There may actually be enough air to 'hiss' out once you get to the surface because it is no longer subject to the pressure of the water.
What are the advantages of a whales lungs collapsing when diving?
don't surface as much
What happens when you go deep sea diving after smoking a menthol?
You will use up your oxygen much more and may get short of breath so if you do go deep sea scuba diving don't smoke a menthol or drink alcohol its dangerous for you. could relate to death.The diving and menthol death is an Urban myth. While smoking is not a good thing to be doing, there is nothing in a menthol cigarette that will effect you later while diving. The myth is that menthol cigarettes have tiny bits of fibreglass which implode a divers lungs at depth.... Not true.See related links for verification.
How can a person is able to breathe underwater?
By having a bubble of air connected to the lungs - like scuba gear.
A scuba diver is working on the ocean floor he takes a big breath and swims to the surface what happends to the air in his lungs?
As he rises , the air in his lungs expands due to a decrease in pressure. If not allowed to exit, his lungs will explode.
How does force affect scuba diving?
Force itself doesn't affect scuba diving. It's more the pressure.The further you go down, the more pressure there is.The more the pressure is, the more it effects the air spaces inside you.As the pressure it is, it compresses the air spaces inside of you, creating what is known as a squeeze. these are painful, and can prove dangerous, if you don't sort them out.To sort them out, you have to eitherHold you nose, and blow against it. (don't let the air come through your mouth!)Swallow and wiggle your jawThe important air spaces are in your ears, which you must equalize, and your lungs, but they equalize naturally when you breathe.
Are oxygenated fluorocarbons used in scuba diving real?
oxygenated fluorocarbons are indeed real and experiments have shown that you can place a mouse in it and it will stay alive however it is not easy to get the fluid out of the lungs afterwards. As a result it is not used for humans in scuba diving in the way it has been portrayed in things like the film; the Abyss. For one thing it would be hard to fill all of the gas pockets in the body, such as the sinuses and pressure on the body would also effect how various physical processes take place. These would probably limit the depth a diver could achieve even if oxygenated flurocarbons were used.
The dangerous link between tasting abilities and smoking tabaco?
the danger of smokind tabaco is that you can get lung cancer and you lungs trun black... the danger of smokind tabaco is that you can get lung cancer and you lungs trun black...
