Question

properties of water
multiple choice: write the letter of the correct answer in the blank.

1. how is cohesion related to surface tension?

a. the water molecules are attracted to objects on the surface of the water.
b. it invites lightweight insects to \walk\ across to continue the water cycle through living organisms.
c. the water molecules stick extra tight to the molecules around and below them creating an elastic \skin.\

1. which property of water makes molecules of different substances, like water and a spider web, stick together?

a. adhesion
b. cohesion
c. surface tension

1. which property of water is responsible for the meniscus curve in a glass?

a. adhesion
b. cohesion
c. surface tension

1. which property of water allows water to resist outside forces?

a. adhesion
b. cohesion
c. surface tension

Explanation:

1. Cohesion is the attraction between water - water molecules. Surface tension is due to the extra - tight sticking of water molecules to those around and below them, creating an elastic "skin", so C is correct.
2. Adhesion is the attraction between different substances. Water molecules sticking to a spider web is an example of adhesion, so A is correct.
3. The meniscus curve in a glass is due to the cohesive forces between water molecules, so B is correct.
4. Surface tension allows water to resist outside forces, so C is correct.

Answer:

1. C. The water molecules stick extra tight to the molecules around and below them creating an elastic "skin."
2. A. adhesion
3. B. cohesion
4. C. surface tension
