What is Solid:
The expression solid is used as adjective that refers to a solid object, firm, dense and strong. Also, it refers to body whose molecules have greater cohesion among themselves than that of liquids.
Solid is one of the 4 main states of matter, the others being: liquid, gas and plasma. Solid bodies are characterized by resisting changes in shape and volume. Generally, solids have a defined shape and volume, as well as a high density, which is why they are labeled as heavy.
See also States of Matter.
Also, there are amorphous solid bodies and crystalline solids. Amorphous solid bodies are characterized because the particles that make up the solid do not have an ordered structure, totally contrary to crystalline solid bodies whose atoms are arranged in an orderly and regular manner, the latter are produced at low temperature and constant pressure.
In the area of geometry, solid indicates a figure or object that consists of 3 dimensions: width, length and depth, therefore, it occupies a place in space and has volume, for example: the pyramid and the cone.
On the other hand, solid is that which is well established or established with true or fundamental reasons, for example: the judge’s ruling was very solid and, therefore, does not allow appeal.
Likewise, the expression solid is found in different contexts. Solid waste applies to all types of waste generated by humans that are different from liquid and gaseous waste. In the area of physics and chemistry, solid solution is the homogeneous mixture that is produced with 2 or more firm substances.
In our daily lives, the term solid can be used to refer to the relationships between two people, whether friendship or as a couple, to indicate that they are strengthened and, therefore, there will be nothing that could cause the breakup of relationships. the relationship.

Properties of solid bodies
The properties or qualities of a solid body are: elasticity arises when a solid recovers its initial shape when it is deformed, hardness like diamond does not allow another solid to harm it; toughness is the resistance that the material faces when faced with fissures or cracks, or inertia is the resistance to changing its rest state; Malleability allows obtaining thin sheets of material without breaking it, likewise, ductility allows obtaining threads from the solid.
Liquid state
The liquid state of matter is observed when the temperature increases and the solid loses its shape until it reaches the liquid state. The particles of liquids are united but their attractive force is weak compared to solid matter.
gaseous state
The gaseous state of matter is characterized because the particles of gaseous materials are widely separated and move quickly and in any direction, causing it to have no defined volume or shape.
