This discussion centers on the relationship between buoyancy, density, and pressure at a depth of 2 atm (approximately 33 feet underwater). It establishes that if a one cubic foot balloon is compressed to half its volume at this pressure, its density doubles. The inquiry further explores whether the density of water at this depth also doubles, questioning the constancy of buoyancy under increased pressure. The conclusion drawn is that while the balloon's density increases, the density of water does not double, thus buoyancy is not constant at 2 atm or deeper.

What is density in terms of mass and volume?6MDM said:Homework Statement
If a one cubic foot balloon is reduced to half the volume at 2atm or 33ft of water and is two times as dense, Is water at that depth also two times as dense making bouyancy constant at 2atm or even deeper?
