Which of the following statements about corrosion is true?

Corrosion is a natural process that occurs when metals interact with their environment, typically leading to deterioration. This process can be influenced by various factors including moisture, oxygen, and the presence of salts, acids, or other corrosive substances. While corrosion cannot be completely eliminated, it can be controlled through various methods such as coating, cathodic protection, and the use of corrosion inhibitors. Recognizing that corrosion is a natural tendency of metals to revert to a more stable state helps in understanding the significance of preventive measures in extending the life of structures and equipment exposed to corrosive environments.

The other statements do not accurately reflect the characteristics of corrosion. For instance, corrosion does not exclusively affect non-metallic materials; it predominantly impacts metals. It commonly occurs in wet or humid conditions rather than primarily in dry conditions. Additionally, while high temperatures can accelerate corrosion processes, corrosion can, in fact, occur at any temperature. Therefore, acknowledging corrosion as a natural process that can be managed allows professionals to implement strategies aimed at minimizing its effects.
