A material with definite properties and definite chemical composition is called a pure substance.
This is a homogeneous mixture.
A pure material is called a substance. It is a form of matter that has uniform and definite composition, with distinct physical and chemical properties.
That field of study is called chemistry. Chemistry deals with the properties and interactions of substances and how they transform through chemical reactions and processes. It seeks to understand the composition of matter at the atomic and molecular level.
A substance that does not appear to be the same throughout is called a heterogeneous substance. This means that its composition varies in different parts of the material, leading to visible differences in color, texture, or composition. Examples include a mixture of oil and water, or a salad with different ingredients.
A substance with identical properties throughout is called a pure substance. Examples include elements (e.g. gold, oxygen) and compounds (e.g. water, salt) that are uniform in composition and have consistent physical and chemical characteristics.
A mixture whose composition is uniform throughout is called Homogeneous Mixture.
A material with definite properties and definite chemical composition is called a pure substance.
This is a homogeneous mixture.
salt water is a type of well mixed mixture called a solution

Light is made up of particles with wave properties called "photons". It has no chemical composition.

A material that is not a mixture and has the same properties all the way through is called a pure substance. Pure substances can exist in two forms: elements and compounds. Elements are made up of only one type of atom, like gold or oxygen, while compounds are made up of two or more elements chemically bonded together, like water (H2O) or salt (NaCl). These substances have consistent properties throughout because their composition is uniform at the atomic or molecular level.
A pure material is called a substance. It is a form of matter that has uniform and definite composition, with distinct physical and chemical properties.
A homogeneous system is part of a system with uniform composition and properties, where the components are evenly distributed and indistinguishable at a macroscopic level. Examples include a well-mixed solution or a single-phase alloy.
In a homogeneous mixture, the composition remains uniform throughout the mixture, meaning all samples taken from different parts will have the same composition. In a heterogeneous mixture, the composition can vary throughout the mixture, leading to different samples having different compositions.
