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