Chemistry - The Central Science Test Review

What is the correct definition of Chemistry?

• the science of the properties, structure, composition, and reactions of matter and the changes it undergoes

• the science of quantities of energy, space, and matter, and the laws that govern them

• the science of the physiology, behavior, and qualities of organisms

• the science of earth's physical structure and substance, and the processes that act on it

Why is Chemistry known as the central science?

• because it joins together physics and math, as well as other natural sciences like biology

• because it is used to study what is at the center of the earth

• because it explains what certain substances are made of

• because it is the class most often taken in the middle of high school
