Properties of Matter - Real-life applications Photo by: Kalim Types of Solids Particles of solids resist attempts to compress them, or push Homeworkhelp together, and because of their close proximity, solid particles are fixed in an orderly and definite pattern.
As a result, a solid usually has a definite volume and shape. A crystalline solid is a type of solid in which the constituent parts are arranged in a simple, definite geometric pattern that is repeated in all directions. But not all crystalline solids are the same.
Table salt is an example of an ionic solid: When mixed with a solvent such Homeworkhelp water, ions from the salt move freely throughout the solution, making it possible to conduct an electric current.
Regular table sugar sucrose is a molecular solid, or one in which the molecules have a neutral electric charge—that is, there are no ions present.
Therefore, a solution of water and sugar would not conduct electricity. Finally, there are crystalline solids known as atomic solids, in which atoms of one element bond to one another.
Examples include diamonds made of pure carbonsilicon, and all metals. Other solids are said to be amorphous, meaning that they possess no definite shape. Amorphous solids—an example of which is clay—either possess very tiny crystals, or consist of several varieties of crystal mixed randomly.
Still other solids, among them glass, do not contain crystals. Because of their slow movement in relation to one another, solid particles exert strong attractions; yet as slowly as they move, solid particles do move—as is the case with all forms of matter at the atomic level.
Whereas the particles in a liquid or gas move fast enough to be in relative motion with regard to one another, however, solid particles merely vibrate from a fixed position.
As noted earlier, the motion and attraction of particles in matter has a direct effect on thermal energy, and thus on heat and temperature.
The cooler the solid, the slower and weaker the vibrations, and the closer the particles are to one another. Thus, most types of matter contract when freezing, and their density increases. Note that the vibration virtually stops, but does not totally stop. In fact, as established in the third law of thermodynamics, absolute zero is impossible to achieve: The lowest temperature actually achieved, at a Finnish nuclear laboratory inis 2.
The behavior of water when frozen is interesting and exceptional. In other words, the molecules begin moving further apart as expected, because—in this temperature range, at least—water behaves like other substances, becoming "less solid" as the temperature increases.Professional College Homework Help for Students.

VIBRATIONS AND FREEZING. Because of their slow movement in relation to one another, solid particles exert strong attractions; yet as slowly as they move, solid particles do move—as is the case with all forms of matter at the atomic level.
