Answer :

The correct answer is :

1) Matter exists in four different natural states: solids, liquids, gases, and plasma.

2) Whether a thing is a solid, liquid, or gas depends on two factors:

a substance's constituent atoms, molecules, or ions are made up of their individual kinetic energies. The particles are typically kept apart by kinetic energy. The intermolecular forces that tend to bind particles together with attractive force.

A substance won't condense into a liquid or solid if the average kinetic energy is higher than the attraction forces holding the particles together. A liquid or solid will develop if the kinetic energy is lower than the attraction forces.

3) A solid is distinguished by its structural rigidity and resistance to external forces. A solid substance, unlike a liquid, does not flow to conform to the shape of its container or, like a gas, expand to cover the entire space.

4) Particles that are organised in three dimensions make up crystalline solids. They have equivalent intermolecular forces between them. They have a distinct melting temperature and are anisotropic. The genuine solids are what they are known as. Diamond, benzoic acid, and other crystalline solids are among examples. The use of diamonds includes the creation of exquisite jewellery and the cutting of glass, among other things.

Amorphous means having no defined shape. Solid particles are arranged erratically in amorphous materials. They do not have equivalent intermolecular forces between them. Additionally, the separation between every two particles varies. They lack a recognisable geometric shape. Amorphous solids are isotropic materials that are also referred to as supercooled liquids. Glass and other amorphous solids are a few examples.

5) Because the intermolecular interactions permit the molecules to move, both the liquid and gas phases are fluid. The materials don't have set shapes in each of these phases; instead, the containers housing them shape them.

6) The ability of a fluid to resist relative motion between two surfaces that are moving at different speeds is known as viscosity. In simpler terms, viscosity refers to friction between fluid molecules or resistance to flow.
