Question

Which of the following is an example of chemical damage?

A. Buildup of mold and mildew
B. Corrosion of metal couplings
C. Exposure to extreme heat or cold
D. Exposure to motor oil and gasoline

Answer 1

Corrosion of metal couplings is an example of chemical damage. When iron is exposed to oxygen and water, it rusts, forming a reddish-orange deposit on the metal surface.

Step-by-step explanation:

Corrosion of metal couplings is an example of chemical damage. Corrosion occurs when metals react with substances in their environment, such as oxygen and water. It results in the degradation and deterioration of metallic materials. For example, when iron is exposed to oxygen and water, it rusts, forming a reddish-orange deposit on the metal surface.
