Amorphous solids include glass, plastic, gels and thin films. An amorphous solid is one of two types of solid, the other type being crystalline. An amorphous solid has no repeated pattern of orientations and positions of its constituent atoms and the bonds between them.Continue Reading
Amorphous solids are possible in most classes of materials, although crystalline solids are more common. An amorphous solid is often formed by cooling a liquid faster than its constituent atoms can arrange themselves into regular patterns. The properties of many amorphous solids are actually somewhat intermediate between solids and liquids. The differences between crystalline solids in atomic arrangement also leads to differences in the way they behave under different conditions.
Crystalline solids have definite melting or evaporation points, regular geometric shapes and form flat surfaces when broken or cut. Amorphous solids melt over a range of temperatures, rather than just one, and lack the other features of crystalline solids. The distinction between amorphous and crystalline is not an absolute one, however, and many materials actually have properties of both. They are just the extremes of a continuum of solid states. At a microscopic scale, it can be almost impossible to tell the difference between an amorphous solid and a crystalline one.Learn more about States of Matter
Common examples of solids are wood, sand, ice, bricks and steel. Examples of liquids include water, blood, wine, coffee and rubbing alcohol. Some common gases are hydrogen, helium, propane, water vapor and gaseous nitrogen.Full Answer >
Collect water from the air by condensing it onto a plastic or glass surface, as outlined on beforeitsnews.com. Place a glass bowl over some grass or other vegetation on a sunny day, and wait about 30 minutes. When the inside of the bowl is covered in condensation, turn the bowl and allow the water to run to the bottom.Full Answer >
Some examples of insulators are glass, plastic and rubber. Insulators block the flow of electricity through them due to the stability of the electrons surrounding an atom. However, the electrons in some insulators, such as glass, move more freely in extremely high temperatures and can become conductors.Full Answer >
Examples of insoluble substances are sand, plastic, wood, metal, glass and cloth. These substances never dissolve in water or any other solvent at room temperature and pressure. Sugars and inorganic salts are also examples of insoluble substances. Insoluble substances cannot be extracted from a solution.Full Answer >
