You think probable to a chemical compound.
But today the theory of the fixed composition is not generally valid.
is a form of matter that has a definite composition and distinct properties.
This is a stoichiometric compound.
substance
You think probable to a chemical compound.
The type of matter with a definite volume but no fixed shape is a liquid. In a gas, there is no definite volume or shape, and in a solid there is a fixed shape and definite volume. A liquid is free to adopt of shape of its container, but its volume is fixed.
Solids are the only phase of matter which have a fixed shape and volume.
They both have definite volume and mass but no definite shape.
Liquids have a definite volume but no definite shape. You can measure the volume easily by pouring a liquid into a graduated container. But as for its shape, it simply adopts the shape of whatever you pour it into.
Today the laws of definite proportions and multiple proportions, applied to chemical compounds, are considered as not genarally valid.Many mixtures (not all !) have a fixed composition depending on the specific application and recipe.

This sounds to me like the definition of an element.
Matter can be classified according to its composition Solid: has a definite shape, mass & volume & are highly rigid. They cannot flow, have high density, are almost incompressible & have any no. of free surfaces. Liquid: has a definite mass & volume but no fixed shape & are less rigid. They can flow & take up the shape of the container in which it is stored. Gas: have a definite mass but have no fixed volume or shape & is not at all rigid. They can flow & take up the shape & volume of the container in which it is stored.
Water. Properties of water are;has definite volume, intermolecular forces of attraction are weaker than in solids, lacks fixed shape(takes the shape of the container) and molecules are far apart

Liquids have no definite shape; they take the shapes of their containers.Gases also have no definite shape, they take up any available space.
Solids are the only phase of matter which have a fixed shape and volume.
