A substance that flows is called "liquid".
A solid substance that has both shape and volume is a material that maintains its form and occupies a fixed amount of space. Examples include metals, rocks, wood, and plastic.
The form of a substance is determined by its molecular structure and arrangement of atoms. This structure dictates the substance's physical properties, such as its shape, size, and state of matter (solid, liquid, gas). Changes in temperature and pressure can also influence the form of a substance.

A molecule or a compound
New substances are formed when matter undergoes a chemical reaction.

A fluid, or a liquid, is difficult to explain but scientifically, it is a substance that has had its molecules spread out through the transfer of thermal energy so that they no longer maintain a permanent shape. In other words, when a substance is heated, its molecules move faster and spread out so that the substance will now form to a non-definite shape.
The possessive form for the noun substance is substance's.Example: The substance's origin could not be determined.
A substance that is lacking a definite shape is a liquid. Liquids take the shape of the container they are in but do not have a fixed shape of their own.
