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