Understanding Man-Made Substances
To differentiate between natural and man-made substances, it’s essential to recognize their origins.
Definition of Man-Made Substances
- Man-made substances, also known as synthetic substances, are created through human intervention, typically in a laboratory or industrial setting.
Examples of Substances
- Water (H2O): A natural compound composed of hydrogen and oxygen, existing in nature.
- Oxygen (O2): A naturally occurring element essential for life, found in the atmosphere and produced by plants.
- Diamond: A natural form of carbon that forms under high-pressure and high-temperature conditions within the Earth.
Nylon: The Man-Made Substance
- Nylon:
- Developed in the 1930s by Wallace Carothers and his team at DuPont.
- It is a synthetic polymer, meaning it is created by chemically combining monomers in a controlled process.
- Used widely in textiles, ropes, and various industrial applications due to its strength and elasticity.
Conclusion
In summary, among the options provided, nylon is distinctly a man-made substance, while water, oxygen, and diamond are all naturally occurring. Understanding these differences is crucial for categorizing materials in various fields, such as chemistry and materials science.
