What is the function of cohesion in water molecules?
A
It prevents water from forming hydrogen bonds.
B
It helps water to dissolve nonpolar substances.
C
It allows water molecules to stick to each other.
D
It enables water molecules to stick to other substances.
Verified step by step guidance1
Understand the concept of cohesion: Cohesion refers to the attraction between molecules of the same substance. In the case of water, this is due to hydrogen bonding between water molecules.
Recognize the role of hydrogen bonds: Water molecules are polar, meaning they have a partial positive charge on one side and a partial negative charge on the other. This polarity allows them to form hydrogen bonds with each other.
Identify the effect of cohesion in water: Due to cohesion, water molecules tend to stick together, which is why water forms droplets and has surface tension.
Differentiate cohesion from adhesion: While cohesion is the attraction between similar molecules, adhesion is the attraction between different substances. This is why water can also stick to other surfaces, but this is not due to cohesion.
Conclude the function of cohesion: The primary function of cohesion in water is to allow water molecules to stick to each other, contributing to phenomena like surface tension and the formation of water droplets.
