_ Crystals
What is a crystal?
How are crystals formed?
What are the 3 ways that crystallization can occur and give examples of each?
Give an example of recrystallization when a solid crystal recrystallizes under heat and pressure.
When does a crystal stop forming?
What is a crystal system, how many are there and how are they identified?
How are diamond and graphite the same? How are they different?
How can the element, carbon, sometimes crystallize into a diamond and other times into graphite?
List some different conditions that might affect crystallization.
True or False? The slower the cooling or evaporation, the smaller the crystal.
What is "amorphous"?
What is a "glass"?
What is polymorphism?
Why does water sometimes crystallize into snowflakes and other times into solid sheets of ice?
