The particles can be individual atoms or elemental molecules or compound molecules. In gases, the molecules are loosely held, and so there is a lot of space between molecules to move freely and constantly. Due to this characteristic, the gas has the ability to fill any container, as well as it can be easily compressed. The matter changes its state from one form to another, when heated or cooled, which is covered under the physical change. So, given below are some processes through which the state of matter can be changed:.
Hence, in this article we have learnt that matter is present in three states, i. Solid, liquid and gas. Further, the state of matter are interchangeable, i.

Key Differences Between Solid, Liquid and Gas The difference between solid, liquid and gas can be drawn clearly on the following grounds: 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.
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.
