LESSON 3: NATURE OF SOLIDS Flashcards
1
Q
● formed when temperature of liquid is low and pressure is high causing particles to come close to each other
● rigid because molecules have fixed positions where particles hardly diffuse
● either crystalline or amorphous (non-crystalline)
A
Solids
2
Q
- ordered in well-defined arrangements
- flat surfaces and angles
- regular shapes with striking beauty
A
Crystalline Solids
3
Q
- do not have an orderly structure
- poorly-defined shapes
- example is glass with an optically transparent fusion
A
Amorphous
4
Q
- the shape of the crystal depends on the arrangements of particles
- unit cell is the smallest portion of crystal and has a complete pattern
- when the unit cell is repeated, crystal lattice is formed
- 7 basic types
A
Crystal Lattice and Unit Cell
5
Q
3 kinds of cubic unit cells:
A
● Simple Cubic - atoms are outside
● Body-centered Cubic - parts of atoms or ions are inside
● Face-centered Cubic - atoms or ions are inside but not arranged
6
Q
change one state of matter to another state of matter.
*KMT is used to explain phase changes
