chemistry is usually classified as what type of science
Chemistry Chemistry occupies an intermediate position in a hierarchy of the sciences by reductive level between physics and biology.[3] It is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level.[4] Examples include plant chemistry (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the properties of the soil on the moon (astrophysics), how medications work (pharmacology), and how to collect DNA evidence at a crime scene (forensics).
Chemical substance Chemical substances exist as solids, liquids, gases, or plasma, and may change between these phases of matter with changes in temperature or pressure. Chemical substances may be combined or converted to others by means of chemical reactions.
Color Electromagnetic radiation is characterized by its wavelength (or frequency) and its intensity. When the wavelength is within the visible spectrum (the range of wavelengths humans can perceive, approximately from 390 nm to 700 nm), it is known as "visible light".
Literature Philosophical, historical, journalistic, and scientific writings are traditionally ranked as literature. They offer some of the oldest prose writings in existence; novels and prose stories earned the names "fiction" to distinguish them from factual writing or nonfiction, which writers historically have crafted in prose.
