Chemistry: The Central Science

Chemistry

is the study of matter and the changes it undergoes.

Matter

is anything that occupies space and has mass.

Physical change

involves changes of state in which the identities of the substances do not change.

Chemical change or chemical reaction

involves substances that are used up and others are formed to take their places.

central science

Chemistry is often called ____ because a basic knowledge of chemistry is essential for students of biology, physics, geology, and many other courses.

The world around us is made up of chemicals: Food, Clothing, Buildings, Our entire body, Medicines.
