What happens too crystals formation if it is cooled quickly?
In rocks large crystals form from very SLOW cooling.
Why is crystallization a much better purification technique than simply washing the crystals with cold solvent?
because sublimation is a method of obtaining a product of high purity; it is best adapted to use with small amounts of material; there is little loss of material in sublimation; and the process of sublimation requires less time and transferring.
What is the difference between crystallization and evaporation?
Crystallization -may be defined as a process which separates a pure solid in the from of its crystals from a solution. Evaporation - Process of separating any substance from its solution by removing water is called evaporation.
Can sugar be seperatd from sugar solution?
Yes, sugar can be separated from a sugar solution by evaporating the water, such as by heating or by using a vacuum. However, if heat is used one must be careful not to overheat the sugar, as it can decompose.
Why are Pegmatite crystals so big?
They are associated with the late stages of granite intrusions and the minerals formed in pegmatites literally had the time to enjoy the benefits of a slow crystallization process from a rich chemical stew produced by the cooling granite.
Crystallization?
A process in which a liquid changes to a solid forming crystals
What happens too crystals formation if it is cooled quickly?
In rocks large crystals form from very SLOW cooling.
What are processes used in obtaining crystals?
The process is called crystallization. Methods are precipitation, melting, evaporation, deposition.
What is recrystallization?
Recrystallization is a process in which rocks actually change. It is whereby the crystals of one mineral slowly convert to few but larger crystals of the same mineral with out melting the rock. It is them followed the the process of neomorphism then metasomatism.2.Crystallization is the (natural or artificial) process of formation of solid crystals from a homogeneous solution or melt, or more rarely directly from a gas. This process is often used as a technique to separate a solute from a liquid solution, bringing it into a pure crystalline phase.
What is the process of crystallation?
According to WIKIPEDIA, "Crystallization is the (natural or artificial) process of formation of solid crystals precipitating from a solution, melt or more rarely deposited directly from a gas."
What is the secound step of a rock cycle?
The second step of the rock cycle is crystallization; the process where liquid rock cools to become minerals/crystals.
What is definition of crystallization?
This is a process where crystals are formed from a super saturated solution that is left undisturbed for a few days. A super saturated solution is formed when no more solute can dissolve in the solution.
The process of minerals formation from magma is called?
Crystallization is when minerals form from magma. Crystallization takes time.

because sublimation is a method of obtaining a product of high purity; it is best adapted to use with small amounts of material; there is little loss of material in sublimation; and the process of sublimation requires less time and transferring.
How does the rate of cooling affect crystal growth in igneous rock?
The most common effect is that more and smaller crystals form than would be formed with slow cooling of the same mass of the same crystalizable material, and the incidence of crystal defects is higher because the rapidity of crystal formation does not permit the correction of initially formed defects by interchange of atoms or other crystal forming units between the liquid and solid phases that can occur during slow crystallization.
What is the difference between crystallization and evaporation?
Crystallization -may be defined as a process which separates a pure solid in the from of its crystals from a solution. Evaporation - Process of separating any substance from its solution by removing water is called evaporation.
Do crystals form in caves?
Depends on what kind of cave it is, a moist cave with certain crystallization remains such as quarts or salt, will probably have crystals growing from the ceiling or on the ground of the inside of the cave after it has dried and the process may continue of the cave gets moistened again by a source of water like rain.
