1

What are the 2 pure forms?

crystalline & amorphous

2

What are the 3 types of mixtures?

physical, dispersion, and intimate mixture

3

Looking at the energy diagram, if the liquid crystallizes in the first transition, what do you get?

crystalline solid

4

1st transition - If the liquid does not crystallize, what do you get?

supercooled liquid

5

what is the second transition?

rubber to glass

What is the building block a crystalline?

unit cell

7

What has a repeating cell unit in 3D and has a melting point?

crystalline

8

What other molecules can be in a crystal lattice?

solvates, hydrates, co-crystals, and salts

9

What does crystallization require to start the process?

nucleation
(can be initiated with seed crystals, reducing temp, adding anti-solvent, and evaporation)

10
