Answer:
- A substance having structural rigidity and has a firm shape which cannot be changed easily is called solid. A water-like fluid, that flows freely, having a definite volume but no permanent shape, is called liquid. Gas refers to a state of matter, do not have any shape but conform to the shape of the container, completely, in which it is put in.
- While solids have certain shape and volume, liquids only have definite volume but not shape, gases neither have shape nor volume.
- The level of energy is highest in gases, medium in liquid and lowest in solids.
- The compression of solids is difficult, liquids are nearly incompressible, but gases can be easily compressed.
- Molecular arrangement of solids is regular and close, but liquids have irregular and sparse molecular arrangement and gases, too have random and more sparse arrangement of molecules.
- The molecular arrangement in solids is well organised. However, the layers of molecules slip and slide over one another, in the case of liquids. In contrast, the particles in gases are not at all organised, due to which the particles move randomly.
- When it comes to fluidity, solids cannot flow, however, liquids can flow and that also from the higher level to lower level. As against this gases flows in all directions.
- The spaces between the molecules and the kinetic energy are minimum in solids, medium in liquid and maximum in gases. So, the motion of molecules is negligible in solids, whereas in liquids, the erratic, random motion of molecules can be seen. Unlike gases, which have the free, constant and random motion of molecules.
- In solids, the particles are held tightly by strong intermolecular attraction, although in liquids the attraction between particles is intermediate. As against this, the particles are loosely held, because the intermolecular attraction is weak.
- The speed of sound is highest in solids, while the speed is a bit slower in liquids and minimum in gases.
- As solid have a definite shape and size, they do not require a container for storage. Liquids cannot be stored without a container. Conversely, for storing gases, a closed container is required.
