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.Know More
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 in States of Matter
Amorphous solids are solids which do not have an crystalline structure. There is no particular order to the make up of these types of solids. When viewed under a microscope or when x-rayed, the molecules that make up the solid are never in the same order from one piece to another.Full Answer >
Whether the solute is a solid or gas, its solubility in water is dependent on temperature such that an increase in temperature can make solids more soluble while gases become less soluble. This means that if the temperature of water is increased by heating it, then the solid solute will dissolve more quickly. However, for gases dissolved in water, the reverse occurs and solubility decreases with an increase in water temperature.Full Answer >
Sublimation is the scientific process in which solids are changed to gases without passing through the liquid phase. Sublimation occurs when temperatures and pressures are below the triple point. The triple point is the temperature and pressure at which substances can coexist in solid, liquid and vapor forms.Full Answer >
The majority of metals listed on the period table of elements are solids at room temperature or 71.6 degrees Fahrenheit, with mercury being an exception since it solidifies at -38.2 degrees. Metals such as cesium, francium and gallium are listed as liquids on the periodic table of elements because they melt at temperatures of between 80.6 F and 98.6 degrees.Full Answer >
