Question

what would happen if a balloon filled with helium was submerged underwater to various depths? relating to pressure please help :) and and @Physics

Answer 1

pressure on the balloon increases with depth...
so naturally rupture of balloon is the first possibility...
increase in the density of helium gas inside the balloon is also possible...
i.e due to compression. Gasses are compressible and hence it might get denser...

Answer 2

ooh thanks so the volume of the balloon would increase because the pressure increases? or decrease according to Boyle's law which states that as the pressure increases the volume decreases inversely????

Answer 3

Yes, the volume of the balloon would decrease and the pressure (and density) would increase within the balloon.

Answer 4

It will decrease according to boyle's law...

Answer 5

The increment of depths causes increment of pressure in a proportional manner.
Thus the volume of a balloon filled with Helium gas will be decreasing with the increment of the pressure.

Answer 6

The volume of the balloon will decrease, as the pressure increases upon it. You might think the He will eventually liquefy, but if this experiment is done at 300 K it is well above the critical temperature for He-4, so it will remain a fluid until it solidifies. However, I think the pressure required to solidify He at 300K is about 10 GPa, whereas even at the bottom of the deepest ocean the pressure does not rise about 100 MPa.

Answer 7

thankyou sooo much!!! i understand it now :)
