Question

Assume that two bottles , bottle A and bottle B are kept on the table.

They both are made of glass.

Bottle A is kept empty ,
Bottle B is fully filled with water such that no air spaces is left.

If both on them fall due to a slight push on the table which of the bottles will break first and why?

Answer 1

I understand that when you make a hole on a bottle filled with water and put the cap on tight the water will not flow out due to the atmospheric pressure acting on the hole.

My confusion is that, lets say the there's some space remaining on the top of the water, when you close the tap, there's still air inside it, so there is pressure from the atmosphere acting on the surface of water inside the bottle. And the hole is at a height h below the surface of the water, so there's also pressure from the depth h of water due to gravity.

So how does the atmospheric pressure on the hole equal the atmospheric pressure on top of the surface and the water pressure due to depth h?

Answer 2

Hey Buddy ! ☺


The bottle #A will break first.

Explanation:-
As the bottle #B is completely filled with water so, the water present in it will absorb the shock when the bottle sTrikes the table due to which the chances of breaking of bottle#B reduces.

Whereas,

The bottle#A is left empty so, the force of impact on the bottle will be more than that of Bottle#B 'cause the shock when the bottle#A hits the ground won't be absorbed due to which the chances of breaking of bottle#A will be more than that of bottle#B.
