Rationale

Putty, cotton clouds are the result of a heat transfer process.

The passage describes the formation of clouds through condensation of water vapor, not as a result of a heat transfer process. While heat can play a role in evaporation, the statement about putty clouds is misleading as it does not accurately reflect the water cycle process described. A) This statement is false because it inaccurately attributes cloud formation to a heat transfer process. The passage explains that clouds form when water vapor condenses back into liquid droplets, which is a process driven by cooling rather than heat transfer. Therefore, the characterization of clouds as a result of heat transfer is incorrect. B) This statement is true as the passage clearly states that a single drop of water is composed of an oxygen atom bonded to two hydrogen atoms, which is represented chemically as H₂O. This is a fundamental fact about the molecular structure of water. C) This statement is also true; the passage emphasizes that water is essential for sustaining life on Earth. It highlights the critical role water plays in various life functions, thus affirming its importance. D) This statement is true as well, as the passage mentions that runoff collects in various bodies of water, including lakes. This accurately reflects the water cycle's process of water accumulation and distribution. Conclusion In summary, the correct answer is that the statement regarding putty, cotton clouds being the result of a heat transfer process is false. The passage outlines the water cycle, emphasizing condensation in cloud formation and the essential role of water in life. Other statements accurately reflect the information provided, reinforcing the understanding of water's composition and its importance in ecosystems.
