Final answer:
A glass can be filled with water above the rim without spilling due to cohesion, which is mainly a result of hydrogen bonds forming surface tension.
Step-by-step explanation:
A glass can be filled with water above the rim without spilling due to cohesion, which is mainly a result of hydrogen bonds forming surface tension. A glass can be filled with water above the rim without spilling due to hydrogen bonds. This happens because of the property of cohesion, where water molecules are attracted to each other, forming a strong bond that keeps the molecules together at the liquid-gas interface.
This is known as surface tension, which allows the water to form a dome-like shape above the rim of the glass without overflowing. Cohesion in water is primarily due to the hydrogen bonds between the water molecules.
The correct option is A.
