Meaning of Solid State

What is solid state:

Solid state means one of the four states of aggregation of matter, whose main characteristic is the opposition and resistance to change in shape and volume.

A good part of the substances that exist are in a specific state that, together with the solid, are called: liquid, gaseous and plasmatic. The word solid derives from the Latin solĭduswhich means strong or firm.

matter in solid state It is composed of a set of particles that are together and orderedand maintain their shape thanks to the cohesion and strong attraction of their molecules.

As the particles of a solid are ordered and with a certain geometric regularity, this gives rise to the formation of various crystalline structures.

Matters in a solid state are one of the most common and observable, they can only move through the oscillation or vibration of their fixed parts and their particles cannot move freely from one place to another throughout the solid.

However, there are materials that can change from an initial solid state and melt after reaching the melting pointthis thanks to the speed of movement reached by the molecules as they overcome the force of attraction and leave their fixed position and their crystalline structure is slowly destroyed.

Solid State Characteristics

matter in solid state It is mainly characterized by having a constant shape and volume.. That is, a matter in a solid state cannot be compressed just by squeezing or pressing it.

Another characteristic that can be added is that when matter is in a solid state and at rest presents a resistance that prevents modifying its malleability and ductility.

However, many solids can be deformed because they have various properties such as the elasticity with which a solid matter can recover its initial state after being deformed). It can also have other properties such as hardness or brittleness.

On the other hand, solid-state materials can increase or decrease in volume when exposed to very high or low temperatures. These phenomena are known as expansion and contraction.

Also, some materials in the solid state can be amorphous, rigid and of high density.

Solid State Examples

There are several examples that demonstrate the solid state of matter, among them we can mention:

  • Salts, which are ionic crystalline solids.
  • The diamond, which is a precious stone.
  • Polyethene is an amorphous solid.
  • Glass, amorphous solid.
  • Graphite, crystalline solid.
  • Sugar is a crystalline solid that can dissolve in water.
  • Sodium chloride is a crystalline solid of ionic type.
  • Ice is a crystalline and molecular solid.

solid state hard drive

It is called solid state hard drive to secondary storage devices or auxiliary memory, used in computer equipment as a replacement for a conventional hard drive.

This hard drive has no moving parts and drastically reduces seek time and latency compared to magnetic hard drives.
