    Bouyante Force
    A steel is much denser than Water. In view if this fact, how do steel ships float?

    Errrrm, how about the fact they are full of air.
    This will dramatically add to their buoyance.

    As Curlyben points out, a boat's average density is less than that of water, thus it floats.

    Curlyben
    Thank you


    Capuchin hi again my friend

    So the ships less dinser because they are from outside made of steel

    But from the inside full of air.

    Yes. Exactly.

    You should see that



    i.e. the average density of the ship is less than the density of the water.

    Therefore it floats!

    Oh feel tired I just came from the uni :(
    I can't even think right now
    I will have some sleep
    Then I will think in this problem.

    I have the same question:

    A tennis ball is made of Rubber that has a density greater than that of water.
    However, a tennis ball will float on water. Explain why?


    Thanx:o

    :D hi am wake and full of energy.

    Well my last answer will be that the ship or the ball are made from the outside from steel
    ( or rubber) but from the inside they are cavernous and fall of air.Therefore, they are
    Bacome less denser then the water's density and the float.

    :p
