Question

When a narrow diameter glass tube is inserted into a body of water, water rises in the tube and its surface inside is concave upwards. Which statement, concerning the strength of the intermolecular forces between glass and water molecules compared to those between water molecules, is accurate?
(1). The forces of attraction between the glass and water are the same as those in water.
(2). The forces of attraction between the glass and water are weaker than those in water.
(3). Intermolecular forces are irrelevant to this situation.
(4). The forces of attraction between the glass and water are stronger than those in water.

Answer 1

Answer:

(4). The forces of attraction between the glass and water are stronger than those in water.

Explanation:

Adhesion is responsible for a meniscus and this has to do in part with water's fairly high surface tension.

Generally the force of attraction between the glass and water is stronger than those in water, hence the concave meniscus is formed,

A concave meniscus, which is what you normally will see, occurs when the molecules of the liquid are attracted to those of the container.

Hence the correct option is option 4.
