Question

Out of solids, liquids and gases, which one has:
(a) Maximum movement of particles?
(b) Maximum interparticle attractions?
(c) Minimum spaces between particles?

Answer 1

A state of matter is one of the several forms that matter may take in physics. In everyday life, four states of matter are visible: solid, liquid, gas, and plasma. Many intermediate states, such as liquid crystal, are known to exist, while certain states, such as Bose–Einstein condensates, neutron-degenerate matter, and quark–gluon plasma, are known to exist only under severe circumstances, such as extreme cold, extreme density, and extreme energy.

Complete answer:
Constituent particles (ions, atoms, or molecules) are tightly packed together in a solid. The interactions between particles are so intense that they can only vibrate rather than move freely. As a result, a solid has a fixed volume and a stable, distinct form. Solids can only change their shape when subjected to an external force, such as being shattered or sliced.
A liquid is a virtually incompressible fluid that adapts to its container's shape while maintaining a constant volume regardless of pressure. If the temperature and pressure are constant, the volume is fixed. When a solid is heated to its melting point and the pressure is greater than the substance's triple point, it becomes liquid.
A gas is a fluid that can be compressed. A gas will not only adapt to the geometry of the container it is in, but it will also expand to fill it. The molecules in a gas have enough kinetic energy that intermolecular interactions have a limited impact (or none at all in a perfect gas), and the average distance between nearby molecules is substantially larger than the molecular size.
(a) Gases have the most particle mobility because they have the most space between them.
(b) Solids have the greatest interparticle attraction, causing them to be close together.
(c) Because of the strong attraction between particles, solids have the smallest amount of space between them.

Note:
A gas has no distinct shape or volume, but it takes up the full volume of the container in which it is contained. A liquid can be turned to a gas by heating it to boiling point at constant pressure, or by lowering the pressure at constant temperature. A vapour is a gas that can be liquefied by compression alone without cooling at temperatures below its critical temperature. When a vapour and a liquid (or solid) are in equilibrium, the gas pressure equals the vapour pressure of the liquid (or solid).
