Identify Natural and Synthetic Fibers

Which of the fibers from the crime scene is a natural fiber and which is a synthetic fiber?

A. Natural or Synthetic? Why?

B. Natural or Synthetic? Why?

Answer:

Based on the information provided, I cannot determine the specific fibers from the crime scene as they are not mentioned in the question. However, I can provide you with some general information to help you identify natural and synthetic fibers.

1) Natural fibers are derived from plants or animals. Examples of natural fibers include cotton, wool, silk, and linen. These fibers are made up of complex organic molecules and are generally biodegradable.

2) Synthetic fibers, on the other hand, are man-made and created through chemical processes. They are made from polymers and often derived from petroleum or coal. Examples of synthetic fibers include polyester, nylon, and acrylic. Synthetic fibers are generally more durable and resistant to wrinkles and shrinkage compared to natural fibers.

To determine whether a fiber is natural or synthetic, you can perform tests such as burning or chemical analysis. Natural fibers tend to burn and smell differently than synthetic fibers. Additionally, microscopic analysis can also help identify the structure and characteristics of different fibers.

However, I hope this information helps you understand the general characteristics of natural and synthetic fibers.
