No substance always has the same composition and properties, unless that substance is only considered in one of the various phases of matter. An element would be the logical choice, but many compounds and even solutions are the same no matter what (of course dependent on phase).
A substance with a constant composition is a pure substance, meaning it is made up of only one type of atom or molecule. This means that the proportions of elements in the substance do not change. Examples include elements like oxygen or compounds like water.

What is always the same no matter how much of the substance you have?
The chemical composition or properties of the substance remain constant regardless of the quantity present.
What does the composition of a substance does not change?
The composition of a substance remains constant if the chemical bonds that hold the atoms together are not broken. This means that the types and numbers of atoms present in the substance do not change, even if it undergoes physical changes like melting or boiling.
What is the homogeneous material with with a variable composition?
An example of a homogeneous material with a variable composition is a solution, where one or more substances are dissolved in another substance. The composition of a solution can vary depending on the amount of solute dissolved in the solvent.
What is the scientific term of substance?
In science, a substance is defined as a type of matter that has a constant composition and distinct properties. Substances can be elements, compounds, or mixtures.
What is the substance with a constant composition that can be broken down into elements?
A chemical compound is a substance with a constant composition that can be broken down into elements through chemical reactions. A compound is made up of two or more different elements chemically bonded together in fixed proportions.
What is a substance with constant consumption?
What is a substance with constant composition
What matter has a definite or constant composition?
Substance
What is the similarties between mixture and substance?
A substance has constant and definitive composition Mixture is combinations of pure substances that have no constant and definitive composition: homogeneous mixture, heterogeneous mixture
What is a pure substance classified as?
A pure substance is classified by having a definite and constant composition. The substance can be either an element or a compound, but what makes the substance pure, is that it does not vary.

Pure substance definition?
A pure substance:cannot be separated into 2 or more substances by physical or mechanical meansis homogeneous, ie, has uniform composition throughout the whole sampleits properties are constant throughout the whole sampleits properties do not depend on how it is prepared or purifiedhas constant chemical composition
What two things are unaffected in physical change?
The chemical composition is not changed.
What is the dielectric constant of mineral spirits?
The dielectric constant of mineral spirits can vary depending on the specific composition and purity of the substance. Generally, the dielectric constant of mineral spirits ranges from around 2 to 3.
