Grinding quartz crystal down to produce sand is an example of a?
Grinding quartz crystals down to produce sand is an example of physical change. When you grind quartz down to sand, you change the physical appearance of the quartz.
Is grinding quartz crystals down to produce sand - an example of a physical change?
No. It would only be a change of state if it changed from a solid to a liquid, or sublimated from a solid to a gas. There are three states. They are solid, liquid and gas. I believe that Plasma is also considered a state but I am not sure of that. Continued from previous answer. Sand is Still a solid. It is small but still solid individual pieces.
Irradiation of quartz that contains traces of aluminum will produce what gem?
The irradiation of quartz containing traces of aluminum will produce an amethyst gemstone. This process can change the color of the quartz from clear to purple, resulting in the formation of amethyst crystals.
Are some crystals eatable?
You can eat some kinds of crystals... salt crystals and sugar crystals, for example. It's probably not a good idea to eat, say, quartz crystals, though.
What is a good example of a crystalline structure--wood or rubber or quartz?
As the name implies, a "crystalline structure" is going to be found in "crystals", hence: quartz.
What mineral appears in transparent hexagonal crystals?
Quartz can appear in transparent hexagonal crystals.
Are hand specimens of microcrystalline quartz single crystals or aggregates of crystals?
Hand specimens of microcrystalline quartz are typically aggregates of crystals rather than single crystals. Microcrystalline quartz is composed of small interlocking crystals that are too small to be individually distinguished without magnification.
How do you use quartz in a sentence?
The material used to manufacture piezoelectric crystals is quartz. Wrist-watch crystals are often made of quartz. Quartz is a transparent mineral. The statement "There are four quartz in an imperial gallon" is faulty, and logically meaningless.
How are crystals different than quartz?
Quartz is a type of crystal. There are many different types of crystals. A crystal is any solid with a regular repeating atomic/molecular structure. Quartz is a crystal that is composed of silicon dioxide. Diamond is a crystal of carbon. Rubies and sapphires are crystals of aluminum oxide. Salt is a crystal of sodium chloride. Even organic compounds, like sugar, can form crystals. Semi-crystalline material is also known, and an example of that is the common plastic HDPE (high density polyethylene).
What is a twin scepters?

Are rock crystals the same as quartz?
Yes! Of course! Because they are both crystals.
What crystals are used in timepieces and electronics?
Piezo electric quartz crystals.
