What term describes the chemical degradation of metals resulting from environmental interactions__________________?
Show answer Hide answer
Answer: C. corrosion
Explanation
Corrosion describes the chemical and electrochemical degradation of metal surfaces by the environment. Moisture and oxygen react with metals to form stable oxide and hydroxide scales. This progressive deterioration weakens the structural integrity of metallic objects over time. Oxidation-reduction reactions drive the electrochemical corrosion processes of active metals. Rusting of iron is the most common everyday example of atmospheric metal corrosion. Environmental factors like salt and acid rain accelerate metal degradation rates.
Engineering infrastructure requires protective coatings and paints to prevent costly corrosion damage. Corrosion prevention saves billions of dollars annually in industrial equipment maintenance. Understanding oxidation mechanisms helps metallurgists design corrosion-resistant metal alloys. Activation refers to initiating a chemical reaction rather than degrading metal structures. Enameling is a protective glass coating applied to prevent metal corrosion damage. Coating is a protective measure applied to surfaces to stop corrosion from occurring.
