in 1964, stephanie kwolek and her team at dupont, a chemical company, were searching for a lightweight fiber that could replace steel in radial tires. kwoleks research led to kevlar, a material five times stronger than steel by weight. the discovery process wasnt without obstacles. kwoleks first attempt resulted in a thin, murky solution. her coworkers thought it should be discarded. kwolek persisted. she spun the solution in a spinneret, a machine used to remove liquid. when the solution was spun, it successfully produced a remarkably strong fiber: kevlar. now, kevlar is used in products such as bulletproof vests. after kwolek retired, she wanted to help students understand the complicated process of making materials like kevlar. she invented the nylon rope trick, a demonstration of how to make long strands of the chemical compound nylon. match the problems with their solutions. kwolek developed the nylon rope trick. kwolek used a laboratory spinneret. kwolek developed kevlar. problem solution kwoleks team needed a replacement for steel in tires. the solution was thin and cloudy. kwolek wanted to demonstrate how to prepare synthetic

Answer

Brief Explanations:

  1. For the problem "Kwolek’s team needed a replacement for steel in tires", the solution is "Kwolek developed Kevlar" as Kevlar was the lightweight fiber found to replace steel in radial tires.
  2. For the problem "The solution was thin and cloudy", the solution is "Kwolek used a laboratory spinneret" as she spun the thin, murky solution in a spinneret to produce the strong fiber.
  3. For the problem "Kwolek wanted to demonstrate how to prepare synthetic", the solution is "Kwolek developed the nylon rope trick" as she invented it to help students understand making materials like Kevlar and demonstrate making long - strands of nylon.

Answer:

Kwolek’s team needed a replacement for steel in tires - Kwolek developed Kevlar. The solution was thin and cloudy - Kwolek used a laboratory spinneret. Kwolek wanted to demonstrate how to prepare synthetic - Kwolek developed the nylon rope trick.
