Why do solids have a definite shape?

Solids have definite shapes and volumes because their atoms and molecules are held together firmly by the strong inter-molecular forces. At low temperatures, the kinetic energy in the solid is usually not enough to overcome these intermolecular forces, so the solid remains in the same state. read more

Any matter that is a solid has adefinite shape and a definite volume. The molecules in a solid are in fixedpositions and are close together. Although the molecules can still vibrate, they cannot move from one part of the solid to another part. read more

This fixed, closely packed arrangement of particles causes a solid to have a definite shape and volume. The above may be true for rigid solids, but it is not true that solids have a definite shape. Many solids may be deformed, and in that process assume a different shape. read more
