Because when matter is solid the molecules are held together and cannot move, but still vibrate in their place. liquid and gas molecules are not held together but a liquid still has a certain volume while a gas does not
It is a characteristic of liquids and gases to assume the shapes of their containers while solids maintain their own shapes.
Liquids and gases can change shape without any change in weight.

Solids have a definite shape and volume. Liquids have a definite volume, but no definite shape - they take the shape of their container. Gases have no definite volume and no definite shape - they expand to fill their entire container.
vaporization
It would be more precise to say that they have no fixed shape; they do have shapes in the sense that they take on the shape of whatever container they are in.
In gases, particles are widely spaced and have high kinetic energy, allowing them to be compressed easily. In solids, particles are closely packed and have strong intermolecular forces that prevent compression. This is why gases can be squashed or compressed, while solids maintain their rigid shape.
Gases don't have a definite shape because the molecules aren't tightly packed together like solids and liquid's molecules are. The molecules in the gas are spread out and move freely about quickly in all directions.
When molecules in liquids and gases are heated they move faster
Gases and liquids are both considered fluids because they can flow and take the shape of their container. They can exert pressure on the walls of their container and have molecules that move freely past each other. However, liquids have higher density and are less compressible compared to gases.

liquids and gases have almost the same molecular structure which makes the alikw
