Why is it easier to squeez an empty bottle compare to filled bottleBest explanation will be highlighted |
|
Answer» Answer:Depending upon HOW you are breaking the bottle, it may actually be harder with water in it. :) But that's not what was asked: To simplify the explanation a bit, if you are dropping the bottle onto a hard surface, you are rapidly transferring momentum from one place to another through the point of contact and in the process the bottle will deform slightly (PROBABLY not visible to the naked eye). If the stress/strain of deformation exceeds certain MATERIAL limits, it will break. If not, it will rebound (i.e. recover it's original SHAPE) and bounce / vibrate for a while. When it is FULL of water, there is a additional mass and subsequently momentum to transfer into the surface in question. That moment of contact may last a bit longer and the structural deformations may be pushed a bit further as the water transfers it's momentum through force on the bottle WALLS down into the surface. That extra force and contact time could push the structure of the bottle past its limits and cause it to break where it may not have if empty. Explanation: |
