Read each question carefully and answer to the best of your ability. Show all your work for calculations.
1. Which of the following best describes surface tension?
The inward force on the surface of a liquid.
The outward force exerted by a liquid on its container.
The tendency of a liquid to resist flowing.
The force that causes liquids to evaporate.
2. What is the primary cause of surface tension?
Adhesive forces between liquid molecules.
Cohesive forces between liquid molecules.
The density of the liquid.
The temperature of the liquid.
3. Water striders can walk on water due to the phenomenon of .
4. Adding detergent to water will typically its surface tension.
5. The units of surface tension are typically measured in .
6. Heating a liquid generally increases its surface tension.
True
False
7. Capillary action is a direct result of surface tension and adhesive forces.
True
False
8. Explain how surface tension allows small objects, like a paper clip, to float on water even though their density is greater than water.
9. Describe one real-world application or phenomenon that is a direct consequence of surface tension (other than water striders).
10. Observe the image below. This illustration depicts the surface of the moon.
Although not directly related to surface tension, analyze the image and describe how the concept of 'surface' is important in understanding celestial bodies like the moon.
