Which of the following statements about the corrosion process is true?

In the context of understanding corrosion, it's important to recognize that the process involves several electrochemical reactions, often leading to the deterioration of metals. If only the second statement is considered true, it suggests that specific factors related to the environment or the nature of the metal involved directly contribute to the corrosion process.

Corrosion is influenced by various elements such as moisture, temperature, pollutants, and the electrical conductivity of the environment. If the second statement highlights something about the conditions or mechanisms that promote corrosion, it underlines a fundamental aspect of how corrosion occurs.

Understanding these factors allows maintenance and preventive measures to be better focused on the right conditions that exacerbate the corrosion process. This can include using coatings, selecting materials with better corrosion resistance, or controlling the environmental factors that lead to increased corrosion rates. Recognizing that only the second statement is true indicates that there's a clear understanding of corrosion mechanisms without being misled by potentially incorrect claims made in the first statement.
