Why do marbles sink in water.
Why does a marble sink in water.
Keep that in mind when using any type of abrasive cleaner on your marble surfaces.
That is why the marble sinks.
And also because of the marbles shape and size.
Ocean liners are made of steel and they float because their density is less than that of the water they float in.
As a result there is a net downward force on the marble.
The ability of a boat to float depends on its average density.
A glass marble placed in a beaker of water sinks to the bottom of the beaker.
Because the marble has a lesser density than water.
I found a way to remove water stains from marble successfully.
The buoyant force which is equal to the weight of the water the marble displaces is smaller than the weight of the marble.
You make the call.
When a marble is dropped into a beaker of water it sinks why are all these wrong explanations.
While this solution worked for me you need to use your judgment as to whether it is right for you.
But back to the question of the hour why does a boat float but a nail sink.
The surface area of the marble is not large enough to be held up by the surface tension of the water.
The weight of that volume of water was less than the weight of the clay and thus the buoyant force was less than the gravitational force.
And also because of the marbles shape and size.
Changing the shape of the clay didn t change the weight of the clay but it changed how much water the clay could displace.
By pushing aside more water the clay boat was able to displace.
Marble is a porous stone that scratches easily.
Why does a marble sink into water but an aircraft carrier which is heavier float.
The clay ball sunk.
That s another reason why even big ships don t sink if they have the right shape.
