Substance
A liquid is a state of matter that has a definite volume but no definite shape. Liquids take the shape of their container but maintain a constant volume.
Matter with a definite composition is a pure substance, such as an element, molecule, molecular compound, or ionic compound.
This is a solid.
Liquids held at a constant temperature definitely doen't have a definite shape but a it most certainly has a definite volume.

Substance, classified as an element and compound. For an element, it cannot be separated into another simplier substance; for a compound, it can be dicomposed into elements using chemical processes.
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.
A substance is any matter that has a fixed composition and definite properties. This means that substances are made up of specific elements in a certain ratio, and they exhibit unique characteristics that can be used to identify and describe them. Examples of substances include water (H2O), salt (NaCl), and oxygen (O2).
Definite chemical composition is when a mineral is made of the same material throughout. Basically when a mineral is only made of one material all the way through, not part iron in one part and then gold in the rest.
The matter state with a definite volume but an indefinite shape is a liquid. Liquids take the shape of their container but maintain a constant volume.
A material with definite properties and definite chemical composition is called a pure substance.
