Crystals are type of solid state bodies whose structural order are well defined and have a unique lattice structures. There is a perfect distance between the various layers in its structure. Crystallinity has big influence on the hardness, density of the body. Non- Crystalline substances are the ones who lack the structural order and do not posses the well defined lattice structure. They tend to have lower density and low melting point as there atoms are scattered. Crystals have high tensile strength while the non crystals are not.

What is the most important property of glass?
It is a noncrystalline solid
Which characteristic provides the best evidence that obsidian rock formed in an extrusive environment?
noncrystalline glassy texture
Does glass melt slowly?
yes it melt very slowly cause glass is noncrystalline and it doesn't have property of liquid, you get me?
What is the mass of granite?
Granite does not have an Atomic Mass, because it is not an element.Granite is a solid mixture of both crystalline and noncrystalline minerals.
Is obsidian extrusive rock?
No. Obsidian is volcanic glass. Glass is amorphous and thus noncrystalline.
What is the atomic mass of granite?
Granite does not have an atomic mass, because it is not an element.Granite is a solid mixture of both crystalline and noncrystalline minerals.
What is the difference between crystalline and non crystalline sugars?
Crystalline is a solid and noncrystalline is a liquid. The word "crystalline" is from the base word "crystal". Salt is an example of a crystalline substance. Noncrystalline sugar is made from crystalline sugar (i.e., granules) and glucose syrup by heating an undissolved mixture of undiluted crystallized sugar and liquid glucose.
How does the arrangement of atoms in a crystalline substance differ from that in non-crystalline substance?
Crystalline solids exhibit cleavage: that is, when you break them, the nature of the break indicates the crystal structure. Thus, grinding a crystal of NaCl (which is cubic) inevitably produces small cubes of NaCl. Noncrystalline solids such as glass break into randomly-shaped pieces. Noncrystalline solids such as glass soften as the temperature increases and have no sharply defined melting point. On the other hand, quartz, which has the same chemical composition as glass but is crystalline, melts sharply at around 1650 degrees Celsius.
What are the essential features of noncrystalline materials?
The do not have a regular and repeating structure.See the Related Questions regarding the difference between amorphous and crystalline materials.
What are diamonds and soot made out of?
Diamond is an allotropic form, crystalline of carbon. Soots are also carbon, but noncrystalline and contain particles of organic compounds.
What are the properties of a glass?
a glass has an amorphous structure (random, noncrystalline)a glass is usually brittle, fracturing easily under stress or sudden shocksilicate glass is usually transparent to visible light, but opaque to ultraviolet lightetc.
