The discussion revolves around the behavior of a rubber ball filled with air when pulled underwater, specifically whether it will eventually lose enough buoyancy to sink. The scope includes theoretical considerations of buoyancy, material properties under pressure, and comparisons to biological adaptations in marine animals.
Participants express differing views on the conditions under which a rubber ball will sink, with no consensus reached on the specific mechanics involved or the implications of density and buoyancy in this context.
Some assumptions regarding material properties, pressure thresholds, and biological adaptations remain unexamined, and the discussion does not resolve the complexities of buoyancy in varying conditions.
If a rubber ball is fill with air, attached to a cord and pulled under water, I assumed it collapses under pressure at some rate.
The question is, will it at some point lose enough bouyancy to sink to the bottom?
"At great depths, CO2 is denser than sea water, and it may be possible to store it on the bottom as liquid or deposits of icy hydrates," Bishop explains. "At depths easy to reach with pipes, CO2 is buoyant; it has to be diluted and dispersed so it will dissolve."
DaleSpam said:I heard once that dolphins use this to be able to efficiently dive deep. They go deep enough that their lungs collapse sufficiently that they become negatively buoyant and can just drop down to their desired depth.
