Verified step by step guidance

Begin by understanding the concept of surface tension. Surface tension is a property of liquids that allows them to resist external force due to the cohesive nature of their molecules.

Water molecules are polar, meaning they have a partial positive charge on one side and a partial negative charge on the other. This polarity leads to hydrogen bonding between water molecules.

These hydrogen bonds create a 'film' on the surface of the water, which is what we refer to as surface tension. This film is strong enough to hold the water slightly above the rim of the glass without spilling.

Consider how surface tension allows small objects, like a needle, to float on water despite being denser than water. Similarly, it allows water to form droplets and maintain its shape.

In this scenario, surface tension is the key property that prevents the water from spilling over the glass, as it holds the water molecules together at the surface.
