What is the main purpose of painting iron to prevent rusting?
Answer and explanation
Correct answer: To prevent iron from coming into contact with air and moisture
Rusting is the oxidation of iron in the presence of oxygen and moisture. A paint coating forms a barrier on the iron surface and prevents air and water from reaching the iron. Therefore, rusting is prevented or greatly slowed. Painting does not change the melting point of iron.
