In the opposite direction, that's why you don't hold your breath when you scuba dive. The air in your lungs is at the correct pressure for your depth, so if you hold your breath as you ascend, the air in your lungs decompresses and takes up more volume.

Interesting how the "deep" balloon resembles a helium-filled balloon being released for a high-altitude flight. In that case, extra envelope material is provided to allow for expansion as surrounding air pressure declines with increasing altitude. The two situations are analogous: the submerged balloon re-expands as water pressure decreases with ascent to the surface; the helium balloon expands as surrounding air pressure declines with increasing altitude. Question: At what depth does the balloon's compressed air exceed the density of water? (I.e., when the balloon is no longer buoyant.)

@geraldfrost47108 ай бұрын
Even solids are compressible, but you have to push really-really hard. To detonate a baseball sized lump of uranium, which isn't quite critical mass, shaped charges are placed around the core. All charges are triggered at the same time. EXACTLY the same time! The same electrical pulse goes down each wire, and each wire is the same length. The baseball is crushed down to the size of a walnut. With the nuculi closer together, it now goes critical and gives off a fraction of a gram of energy. But, you can see how much effort is required. We live in a very specific, very constant environment. It tickles the brain to see other environments.

If you guys are interested, I could do a follow up test later with the balloon free floating in the chamber. Theoretically, once the weight of the displaced volume of water by the collapse balloon is lower than the weight of the balloon rubber, we should see it start to sink if the balloon rubber has a specific gravity greater than 1.
@jaquigreenlees8 ай бұрын
@@TheDropzoneChannel it doesn't have a specific gravity of less than 1, this vid shows that since there is no sinking at all as the gas compresses under the water pressure. The compression most definitely reached the point where the gas buoyancy in water was less than the weight of the rubber.
@RustyDust1018 ай бұрын
@@DounutCereal Correct. The buoyancy goes down. A lot. Equal to the volume change in percent. So the first ten meters are the most noticeable. After that the percentile change drops rapidly until you only get minute changes in buoyancy the deeper you go. But yes, that is EXACTLY the problem why you as a diver ALWAYS have to check your depth gauge regularly, especially in areas with great depth but also great visibility. The change in light in those areas is virtually impossible to notice in the first 40 meters. However your sink rate goes faster and faster. When you notice your depth gauge to drop rapidly, check if your bouyancy compensator is still holding air. If not, your in a LOT of trouble. That's the time you have to think about shedding your ballast AND carefully, very, very carefully inflating your diving vest. Because once you've reached a certain point of depth the buoyancy in your vest won't be enough to keep you neutral if you are still carrying ballast/lead. Very dangerous indeed. But if you DO drop your ballast you also have to be extremely (!) careful about ascending again because you have nothing to keep you down once the vest starts to inflate again as soon as you begin to ascend and the pressure drops. The higher you go, the faster the percentile increase in volume, thus buoyancy, making it more and more difficult to keep under water. Which may result in hyperbaric pressure accidents, which are the absolute number one killer in diving accidents. The bends are mild compared to that; hyperbaric accidents kill more reliably.

Interesting question. My first thought was that since the gas is in a flexible container it can't really be liquified this way. I think. Butane would be a good gas to test as it liquifies easily. Compressing air causes it to heat up, however if constrained it will liquify as it cannot expand. Unless the water surrounding the air counts as the non-compressable container. I imagine it would need compressed more than this test rig can do. SCUBA air cylinders (the high pressure steel ones we used) are pressurised to up to 250 bar, the pressure equivalent of 2.5km deep in the ocean and the air is still gaseous, you could tip the cylinder upside down, open the valve and only air would come out.
