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 about States of Matter
The five phase changes of matter are solids, liquids, gases, plasmas and Bose-Einstein condensates. Elements are able to move between these phases when certain physical conditions exist.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 >
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 >
Total soluble solids are solids that are dissolved within a substance. A common total soluble solid is sugar. The technique of measuring the concentration of total soluble solids is called refractometry, and it is used extensively in the food industry.Full Answer >
