Because their atoms do not have enough energy to move.
The atomic bonds hold atoms in structured position.
Solids are substances which have a fixed volume and fixed shape. Liquids, on the other hand, have a fixed volume but no definite shape. Finally, gases don't have a definite volume or shape.
Solids are rigid and incompressible. Liquids have fixed volume but match their container. Gases completely fill their container.
Simply, Solids have fixed shape and volume because the particles are very , very close to each other . Volume of liquid is the space which is occupied by this liquid, so it's fixed unless you cool this liquid or heat it and it takes the shape of its container As for the gases, the particles are very apart from each other and move freely, so they cannot have a fixed volume or shape and this is due to the attraction force between particles
It sounds like you are studying liquids, solids and gases.A liquid doesn't have a definite shape; it will shape like any container you pour it in.A gas doesn't have a definite volume; you can keep it at high pressure or low pressure and it will squeeze.A solid is the third type of physical state.
A solid has a definite shape and volume. (but the volume may change with temperature)A liquid has a definite volume but not a definite shape, and a gas has no definite volume or shape.
Solids have a fixed volume or shape at room temperature or pressure.
fixed shape
Yes they do. Liquids have no fixed shape and gases have no fixed volume.

Solids.
All solids have a fixed shape unless acted upon by a force. If the temperature remains constant they have a fixed volume.
They are both incompressible, and they have a fixed volume at a fixed temperature.
