What is Crystalline vs. Amorphous and Liquid? How do you understand that?

The difference between crystals and non-crystals: there are standards for the atomic arrangement of crystals, such as most metal materials, edible salt, and ice, and there is no standard for the atomic arrangement of noncrystals (such as laminated glass, bitumen, paraffin), and crystals have a certain melting point, not those that crystals do not have。The melting of the crystal must be achieved so that the melting point can be melted by endothermic reaction again, not that the crystal only needs to absorb the endothermic reaction to gradually loosen and thicken.

There is a difference between the image of the melting crystal and the amorphous image. Crystals are chemical substances produced by repeated arrangement of atoms, positive ions or molecular structures in three-dimensional space in a regular and regular manner according to certain regularities.

There is no certain standard design for amorphous products, such as laminated glass, pine resin, paraffin, etc. Its physical properties are consistent in different orientations and are called "anisotropic". It does not have a solid melting point.

For this reason, some people call amorphous "low-temperature liquid" or "liquid with little liquidity". Crystals are self-normative, while amorphs are not. Difference Between Crystalline and Amorphous:

Self-norm is different, the arrangement is different, friends of the opposite sex and the melting point are different. There are various types of crystals, and most of the amorphous ones are anisotropic. The crystal has a definite melting point, and the amorphous has no fixed melting point, and the ambient temperature continues to rise with heating during the whole process of its melting.

> crystals are molecules that make up matter, arranged in an orderly manner according to certain regularities. If we assume that the molecular structure first constitutes a high-quality strip brick, then a non-standard ball is built from the strip brick. Then, this strip-shaped brick is called monocrystalline, and this ball is called polycrystalline.

It is not the crystal, on the contrary, that the molecules that make up matter are arranged in a chaotic manner. In other words, the molecular structure is made up of gravel, stones, bricks of different sizes, concrete, and then this thing forms an irregular ball.

In general, you can find that single crystals are characterized by various characteristics because they look different from different directions, while polycrystalline and amorphous are all one ball, so they are said to be anisotropic. The melting point is the necessary ambient temperature from solid to liquid, we can understand that the ball melts into water, destroying the force between the bricks and the bricks, so whether it is polycrystalline or single crystal, it is all the force between the bricks and the bricks, so they have a definite melting point, and in the whole process of melting, the endothermic reaction only keeps increasing the molecular potential energy, and the ambient temperature will not change. It is not the melting of crystals, the destroyed items are not clear, but who is actually in the middle of whom, so they do not have a stable melting point, and the whole process of melting maintains the continuous increase or decrease of the ambient temperature.

The so-called crystal is that there is a fixed melting point and boiling point, while the non-crystal is that there is no fixed melting point and boiling point, and the crystal is formed by a certain regular arrangement, while the non-crystal is produced by the disorderly arrangement of molecules.

Solids are divided into crystalline and amorphous, crystals have a regular natural shape, amorphous is an irregular natural shape, liquids have a certain volume, but there is no fixed shape.

Water is amorphous. Because crystals have the following properties:

1. The crystals formed by natural condensation and without external interference have a neat and regular geometric shape, that is, the self-normity of the crystal.

2. The crystal has a fixed melting point, and the temperature remains constant during the melting process.

3. Single crystals have the characteristics of anisotropy.

4. The crystal can make X-ray diffraction occur regularly.

Whether the X-ray diffraction phenomenon can be produced on macroscopic staking is the main method to determine whether a substance is a crystal or not.

5. The crystal plane angle corresponding to the crystal is equal, which is called the conservation of the crystal plane angle.

1. Amorphous is not necessarily liquid, amorphous refers to the material with disordered structure or short-range orderly and long-range disordered, and the molecules (or atoms and ions) that make up the substance are not arranged regularly in space as a solid, and it does not have a certain regular shape. Its physical properties are the same in all directions, which is called isotropic. It does not have a fixed melting point, so some people call amorphous a supercooled liquid or a liquid with very little fluidity.

The vitreous body is typically amorphous, so the amorphous state is also called the vitreous state. Important vitreous substances are: oxide glass, metallic glass, amorphous semiconductors and polymer compounds.

2. Amorphous does not have a fixed molten point, as the temperature increases, the substance first softens, and then gradually thins from thick to fluid, with a certain melting point is the macroscopic characteristic of all crystals, and it is also the main difference between crystalline and non-crystalline.

Definition or Explanation During the melting and solidification process of a substance, when the temperature of the solid and liquid states coexists, the temperature remains the same, and this type of solid substance is called a crystal. In the process of melting and solidifying, the temperature of the substance is constantly changing, and there is no obvious melting point and freezing point, this kind of solid substance is called amorphous. (2) Explain the difference between crystalline and amorphous.

Crystals have a fixed melting point, and during the melting process, the temperature remains constant at all times. Such as: ice, sea waves, various metals, etc.

An amorphous does not have a fixed melting point, and its temperature increases with heating during its melting. Such as: glass, rosin, wax, etc.

Crystal: A solid with a regular shape formed by the arrangement of atoms, ions or molecules according to a certain spatial structure. There is a fixed melting point. For example, ice, crystal, salt, alum, etc.

Amorphous: A solid that is amorphous in shape and in the arrangement of atoms inside, and has no fixed melting point. For example, rosin, glass, beeswax, asphalt, etc.

Some substances can be both crystalline and amorphous, such as natural quartz is crystalline and melted quartz is amorphous.

Particles like salt, sugar, alkaline noodles, and monosodium glutamate are all solid with regular geometric shapes, and people call such solid substances crystals.

Crystals have a fixed melting point, not crystals that don't.

Solid matter is divided into crystalline and amorphous, and most solid matter in nature is crystalline.

Compared with amorphous, crystals have certain geometric shapes, such as table salt, quartz, calcite, etc.

Amorphous such as glass, rosin, paraffin, asphalt, etc., do not have a certain geometric shape.

Crystals have a fixed melting point, while amorphous ones soften over a range of temperatures.

Crystals are anisotropic, while non-crystals are isotropic.

Some properties of crystals, such as optical properties, mechanical properties, thermal and electrical conductivity, mechanical strength, solubility, etc., are often different when determined from different directions of the crystal.

In short, an amorphous substance is a solid substance that is structurally disordered.

In a nutshell:

Crystals: The internal atoms are arranged in a near-range order and a long-range order.

Amorphous: The internal atoms are arranged in an orderly manner, and the remote is out of order.
