Kinetic Theory of Matter
|
Matter is made up of atoms that are in constant motion.
|
|
|
Solid
|
Definite shape & volume; tightly packed, low energy particles
|
|
|
Liquid
|
Indefinite shape & definite volume; less tightly packed, more energetic atoms
|
|
|
Gas
|
Indefinite shape & volume; random motion, high energy; big spaces
|
|
|
Plasma
|
Indefinite shape & volume; same as gas but particles have +/- charges
|
|
|
Amorphous Solid
|
a solid that changes shape under pressure; oobleck
|
|
|
Endothermic
|
energy is absorbed
|
|
|
Exothermic
|
energy is released
|
|
|
Melting
|
solid to liquid; endothermic
|
|
|
Vaporization
|
liquid to gas; endothermic; hot, fast process
|
|
|
Evaporation
|
liquid to gas; endothermic; slow, cool process
|
|
|
Ionization
|
gas to plasma; endothermic
|
|
|
Deionization
|
plasma to gas; exothermic
|
|
|
Condensation
|
gas to liquid; exothermic
|
|
|
Freezing
|
liquid to solid; exothermic
|
|
|
Sublimation
|
solid to gas; endothermic
|
|
|
Deposition
|
gas to solid; exothermic
|
|
|
Thermal Expansion
|
almost all matter expands as it heats up & contracts as it cools down
|
|
|
Direct Relationship
|
when one increases, the other increases
|
|
|
Indirect Relationship
|
when one increases, the other decreases
|
|
|
Boyle’s Law
|
as pressure decreases, volume increases
|
|
|
Charles’ Law
|
as temperature increases, volume increases
|
|
|
Lussac’s Law
|
as pressure increases, temperature increases
|
