Water readily sticks to many other substances, a property called ______. Water readily sticks to many other substances, a proper
Ahat [919]

Answer:

Option (2)

Explanation:

Cohesion is usually defined as the contrasting property by which the water molecules are attached to one another, and adhesion is the property by which the molecular substances are linked to the molecules of other substances.

Since, the water molecules are able to form inter-molecular hydrogen bonding, so they are comprised of strong cohesive force.

And, as the water molecules are able to stick to the walls of the container, so they tend to show more of the properties for adhesion.

Thus, according to the given condition, water molecules are sticking to other substances and this is the property of adhesion.

Hence, the correct answer is option (2).
