1) A gas filled freely collapsible balloon is pushed from surface level of a lake to a depth of 100 m. Approximately what percentage of ots original volume will balloon finally have? Assume that gas behaves ideally.

DEAR ALPHA,

using the relation , p1v1=p2v2

p1=pressure at the surface (= 1 atm)

p2=p1+dgh              where d= density of water

                                       g=grav force

                                        h=height(here 100)

then we can find the final volume.
