Substances, materials, and ingredients are fundamental concepts used to describe the components that make up the physical world. A substance is a form of matter with a definite chemical composition and distinct properties. For example, water (H2O) is a substance, as is iron (Fe). Substances can be pure elements or compounds. Materials are broader terms referring to a collection of substances or a single substance that has been processed or manufactured for a specific use. Examples of materials include steel, wood, plastic, and glass. Materials are often characterized by their physical properties such as strength, flexibility, conductivity, and durability, which determine their suitability for various applications.

Ingredients are the individual components that are combined to create a mixture or a product, particularly in the context of food, pharmaceuticals, or cosmetics. For instance, flour, sugar, and eggs are ingredients in a cake. In a chemical reaction, the starting substances are often referred to as reactants or ingredients. The distinction between these terms can sometimes overlap. For example, sugar can be considered a substance (a pure compound) and also an ingredient when used in baking. Similarly, a material like concrete is composed of various substances (cement, aggregate, water) and is itself used as a material in construction. Understanding the nature and properties of substances, materials, and ingredients is crucial across numerous fields, including chemistry, engineering, manufacturing, and culinary arts, enabling the creation, analysis, and manipulation of matter.
