What Is Chemistry?
Matter is anything that has mass and occupies space.
Chemistry is the study of the composition of matter and the changes that matter undergoes.
Chemical changes that occur in leaves can cause brilliant displays of color.

5. 1.1
What Is Chemistry?
Because living and nonliving things are made of matter, chemistry affects all aspects of life and most natural events.

Pure and Applied Chemistry
How are pure and applied chemistry related?

14. Pure and Applied Chemistry
1.1
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.

15. Pure and Applied Chemistry
1.1
Pure and Applied Chemistry
Pure research can lead directly to an application, but an application can exist before research is done to explain how it works.

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.
Long, thin nylon fibers are woven into the fabric used in this backpack. Other objects that can be made from nylon are jackets, fishing lines, toothbrush bristles, and ropes.

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.

18. Pure and Applied Chemistry
1.1
Pure and Applied Chemistry
Technology
Technology is the means by which a society provides its members with those things needed and desired.
Technology allows humans to do some things more quickly or with less effort.
There are debates about the risks and benefits of technology.

Chemistry can be useful in explaining the natural world, preparing people for career opportunities, and producing informed citizens.

21. Explaining the Natural World
1.1
Why Study Chemistry?
Explaining the Natural World
Chemistry can help you satisfy your natural desire to understand how things work.

22. 1.1
Why Study Chemistry?
Preparing For a Career
Many careers require knowledge of chemistry. A photographer uses chemical processes to control the development of photographs in a darkroom.
Even after the invention of the digital camera, many photographers still work with film. They use chemical processes to develop film and produce prints in a darkroom. Inferring Why isn’t film developed under natural light conditions?

23. Being an Informed Citizen

Why Study Chemistry?
Being an Informed Citizen
Knowledge of chemistry and other sciences can help you evaluate the data presented, arrive at an informed opinion, and take appropriate action.
By registering to vote, these citizens in Chicago, Illinois, can have a say in the decisions made by their government. Those decisions include how much money to provide for scientific research.
