What is Chemistry?

Ever wonder why sugar dissolves in your tea or how batteries power your devices? That's chemistry in action! Chemistry is the study of the composition, structure, and properties of matter. It examines the processes that matter undergoes and the energy changes that accompany these processes.

Contrary to popular belief, "chemicals" aren't bad things to avoid. A chemical is simply any substance with a definite composition. Water, sugar, and carbon dioxide are all examples of chemicals we encounter daily.

Chemistry branches into several specialized fields. Organic chemistry studies carbon-containing compounds, while inorganic chemistry focuses on non-organic substances. Physical chemistry examines properties and energy changes, and analytical chemistry identifies components in materials. Biochemistry explores substances in living organisms, and theoretical chemistry uses math and computers to predict chemical behavior.

Did you know? Chemistry is often called the "central science" because it connects physics, biology, geology, and other sciences. Once you understand chemistry, you'll see the world differently!
