Based on Figure 1, which of the following best describes how the properties of water at an air-water interface enable an insect to walk on the water's surface?
Understand the Problem
The question is asking which property of water at the air-water interface allows an insect to walk on the surface, with reference to a provided diagram. It requires understanding of water's molecular interactions and their effects on surface tension.
Answer
D) Hydrogen bonds between molecules at the surface of the water provide surface tension.
The final answer is D) Hydrogen bonds between molecules at the surface of the water provide surface tension, which allows the water surface to deform but not break under the insect.
Answer for screen readers
The final answer is D) Hydrogen bonds between molecules at the surface of the water provide surface tension, which allows the water surface to deform but not break under the insect.
More Information
Surface tension is a result of hydrogen bonds between water molecules at the surface. It allows the water surface to hold the weight of small objects, such as insects, without breaking.
Tips
A common mistake is to confuse the types of bonds involved. Remember, it is hydrogen bonds, not covalent or ionic, that contribute to surface tension.
