# Why do we say water is cohesive?

May 15, 2018

Cohesion refers to the way that water molecules stick together.

#### Explanation:

Cohesion is one of the most important properties of water. For example, it allows water to move in long streams through the vascular tissue of plants. It also results in high surface tension, which allows some pond insects to move across its surface.

Cohesion occurs because the various water molecules (${H}_{2} 0$) are attracted to each other by hydrogen bonds.
