Read each question carefully and provide your best answer. Some questions may require critical thinking and application of concepts related to surface tension.
1. Which of the following best describes surface tension?
The tendency of a liquid surface to expand.
The cohesive forces between liquid molecules at the surface.
The adhesive forces between a liquid and a solid surface.
The resistance of a liquid to flow.
2. Water striders can walk on water due to:
High density of the water.
Their lightweight bodies.
Strong surface tension of water.
The presence of air bubbles.
1. Surface tension is caused by the forces between liquid molecules.
2. Adding a to water can reduce its surface tension.
3. The shape of a liquid droplet is primarily determined by its and gravity.
1. Explain why water forms spherical droplets on a waxed surface.
2. Describe one real-world application of surface tension.
1. Hot water generally has a higher surface tension than cold water.
True
False
2. Surface tension allows some insects to walk on water.
True
False
Analyze the diagram below and answer the question.
3. Although this image shows a surface, how is the concept of surface tension different from what is depicted here?
