Ask AI: write a paragraph that includes compounds about the chemistry of roller coasters

Roller coasters are thrilling examples of physics and engineering that also involve interesting chemistry, particularly in the materials used to construct them and in the coatings that ensure their safety and durability. Steel, a crucial component in roller coaster design, is an alloy primarily made of iron and carbon, with specific compounds added to enhance its properties; for example, chromium can be added to form stainless steel, which is resistant to corrosion. The paint used to coat roller coaster tracks often contains epoxy resins, which are thermosetting polymers known for their excellent adhesion, chemical resistance, and protective qualities. Furthermore, the lubricants applied to roller coaster wheels and tracks to reduce friction often include complex hydrocarbon compounds, which ensure smooth operation and help prolong the lifespan of the ride. Through a combination of these chemical compounds, roller coasters are able to provide both the excitement and safety that riders expect.
