  1. 1.1 What Is Chemistry?

  2. 1.1 What Is Chemistry? • Chemistry is the study of the composition of matter and the changes that matter undergoes. Matter is anything that has mass and occupies space. Matter = STUFF

  3. 1.1 What are Pure and Applied Chemistry? • Pure chemistry is the pursuit of chemical knowledge for its own sake. • Applied chemistry is research that is directed toward a practical goal or application.

  4. 1.1 • How are pure and applied chemistry related? • Pure research can lead directly to an application, or an application can exist before research is done to explain how it works.

  5. 1.1 Pure and Applied Chemistry • Nylon • In the early 1930’s, Wallace Carothers produced nylon while researching cotton and silk. • A team of scientists and engineers applied Carothers’s research to the commercial production of nylon.

  6. 1.1 Pure and Applied Chemistry • Aspirin • Long before researchers figured out how aspirin works, people used it to relieve pain, and doctors prescribed it for patients who were at risk for a heart attack. • In 1971, it was discovered that aspirin can block the production of a group of chemicals that cause pain and lead to the formation of blood clots. This is an example of pure research.

  7. 1.1 Why Study Chemistry? • Chemistry can help explain the natural world, prepare people for career opportunities, and produce informed citizens.
