Chemical substances can exist in several different physical states or phases (e.g Chemicals are substances that are made up of mass and volume, have a fixed chemical composition and specific properties, and cannot be broken down into other components without breaking chemical bonds. Solids, liquids, gases, or plasma) without changing their chemical composition
Substances transition between these phases of matter in response to changes in temperature or pressure. Explore acids, bases, polymers, pharmaceuticals, and more in everyday life. Chemistry is the study of substances—that is, elements and compounds —while biology is the study of living things
Learn how to safely handle chemicals, the effects of certain toxins, which substances are controlled or managed, and safer alternatives.

Another example is when you dissolve salt into a cup of water. Search chemicals by name, molecular formula, structure, and other identifiers Find chemical and physical properties, biological activities, safety and toxicity information, patents, literature citations and more. For example, pesticides in water or artificial colorings in food are “chemicals.” but, chemistry sees chemicals somewhat differently
It is an element, an alloy, or a compound made up of two or more elements combined in a fixed ratio.
