Why a Full Water Bottle Doesn't Collapse

When a water bottle is filled to the brim, the water molecules are incompressible. This means that no matter how much pressure is applied to the bottle, the water molecules cannot be squeezed closer together, and the bottle does not collapse. This is due to the nature of water molecules and the lack of space for them to move closer together.

Pressure and Incompressibility

The incompressibility of water is a result of the strong hydrogen bonds between its molecules. These bonds prevent the molecules from being compressed, even under high pressure. As a result, the water maintains its volume and the bottle remains intact.

Conclusion

In summary, a full water bottle does not collapse because water molecules are incompressible due to the strong hydrogen bonds between them. This prevents the molecules from being squeezed closer together, maintaining the volume of the water and the integrity of the bottle
