    assuming that the container is tightly sealed and lig.on kaayo, yes. Same pressure as sa illom.

    Below is coming from a college drop-out kay wala kapasa ug Physics.

    Depende sa imong garapon. But assuming nga dili gyud siya macompress nga garapon, ang pressure sulod sa tightly sealed garapon dili mausab regardless of height.
    This particular pressure is called liquid pressure i.e the weight of the water divided by the area of the garapon bottom.
    Since ang density sa tubig sa garapon mao ra gihapon ug tubig dili macompress, ang weight sa tubig is pareha ra hence pressure inside garapon is same.

    di kaha mabuak ang imong garapon anah inig abot na nimu sa ilawom TS?knowing nga kusog au ang pressure..

    Mawala na ang pressure...mogawas na ang hangin sa garapon kung sudlan ug tubig. Maglisud na ug lutaw imo garapon.

    Hehe most people are assuming na mabuak ang garapon. The TS did not specify the depth. Sure, mabuak jud ang garapon if maka 1000ft na guro ka (safest depth for humans to dive so I think an ordinary glass jar kay maboak na). The TS could be talking about the pressure 10ft below water surface. Or 100ft, or 1000ft. But that is irrelevant kay ang question is if same ang pressure sa water inside a container that came from a certain depth if imo syang dad.on sa surface.

    Static fluid pressure at a given depth kay dili mag depend sa total mass or total volume sa liquid. If we're talking about just one type of liquid (in this case, seawater) constant ra tanan values. Ang variable ra is the height/depth.

    The pressure of seawater at 100ft is different from the pressure at 1000ft, so if ang TS is mokuha ng tubig at depth 1000ft and ang iyang container kay tightly sealed ug sturdy, the pressure inside the container is the same as the pressure of water at 1000ft.

    Since ang jar is tightly sealed, the pressure inside will be undisturbed and will be the same even if you bring the container in the surface.

    pero given nga successful nga nakakuha ka ug tubig from the abyss, i think pag saka nimo kay pareho lang ang pressure sa surface pag open nimo kay wala namay volume involved. (again sa akoa lang ni. ogob kaayo ko ug science)
    parehas ko ug idea ani...
    mao grabeh ang pressure sa ilawom najud sa dagat ky sa volume of water and atmosphere nga nag.doot didtong area.ha...mas lawom mas grabeh ang pressure kay maapektohan man sa height....(mao ba to leksyon sa highskul namo?)ehehhe

    hahaha daghana replies gud ani....

    kani ra ako matubag, tried experimenting this before....

    you can't compare water with air, if you bring a 1.5 liter botther filled with air, at 20 feet it will be compressed at half its volume, whereas if you bring 1.5 liter bottle filled with water and no air, d xa ma compressed.

    the experiment that i did was i brought an open 1.5L bottle at about 100ft sealed it shut and when we went up it did not build up, wa sad xa mosirit. Next is i brought another bottle and filled it with air at 40ft depth. and closed it. at around 10 ft mura na xa ni bulge, at surface ni pop na ang cap. so dili mabuak ang jar kung imo e fill ug water then e close nya dalhon sa taas.

    as for the question sa uban about ngano dapat mag decompress ang diver before mo surface, this is the answer

    when you are diving using compressed air (dili na xa pure oxygen gigamit sa dive), your lung tends to have the same volume because you are constantly breathing as you descend. so even if the pressure is greater, your lung is equalized by your inhalation. when you ascend, you must stop at intervals to equalize the pressure in your lungs with the surrounding water pressure kay if mag paspas ka ug saka, then daghan air imo lungs, mo expand na xa nya mo pop imo lungs.



    hope this helps
