Question

Discuss the three states of matter: solid, liquid and gas on the basis of molecular models.

Answer 1

Hint: We have to know that a state of matter is one of the unmistakable structures in which matter can exist. Four states of matter are discernible in regular daily existence: strong, fluid, gas, and plasma. Many moderate states are known to exist, like fluid precious stone, and a few states just exist under outrageous conditions, for example, Bose–Einstein condensates, neutron-degenerate matter, and quark–gluon plasma, which just happen, separately, in circumstances of outrageous chilly, outrageous thickness, and incredibly high energy. For a total rundown of all intriguing conditions of issue, see the rundown of states of matter.

Complete answer:
Solids:
Here the particles are firmly pressed that there is no or less intermolecular space and there is high intermolecular power of force (power of union). The atoms don't move about their mean position and consequently solids have an unequivocal shape and volume.
Fluids:
Here the particles are less firmly pressed when contrasted with solider and furthermore there is lesser powers of intermolecular force. The intermolecular distance is more noteworthy than that in the solids. Consequently, they don't have a clear volume at a given temperature.
Gases:
In a gas, particles are in persistent straight-line movement. The active energy of the atom is more noteworthy than the appealing power between them, in this manner they are a lot farther separated and move unreservedly of one another.

Note:
Plasma:
We need to remember that in plasma, electrons are torn away from their cores, framing an electron "ocean". This enables it to direct power. Like a gas, plasma doesn't have a clear shape or volume. In contrast to gases, plasmas are electrically conductive, produce attractive fields and electric flows, and react emphatically to electromagnetic powers. Emphatically charged cores swim in a "ocean" of unreservedly moving disassociated electrons, like the manner in which such charges exist in conductive metal, where this electron "ocean" permits matter in the plasma state to lead power.
