STATES OF MATTER
-
-
-
PHASE CHANGES
transformations from one phase to another, occur when energy is added or removed
-
Deposition (gas-solid)
Sublimation (solid-gas)
Condensation (gas-liquid)
Melting (solid-liquid)
Freezing (liquid-solid)
Vaporization (liquid-gas)

-
SOLIDS
crystalline solid, amorphous solid,
-
-
-
Relationship between atomic radius and edge length a of a body-centered cubic unit cell is r=cubic 3/4 times a
-
GASES
-
Boyle's Law
-
constant temperature,constant amount of gas
-
Avogadro's Law
-
-
constant temperature,constant pressure
-
LIQUIDS
surface tension is amount of energy required to stretch or increase the surface of liquid by a unit area
-
cohesion = intermolecular attraction between like molecules when greater than adhesion, a depression of liquid in capillary tube.
Adhesion= an attraction between unlike molecules when greater than cohesion, the liquid will rises in capillary tube
Viscosity is a measure of a fluid's resistance to flow. If strong intermolecular forces, high viscocity.
TYPES OF CRYSTAL
IONIC CRYSTALS
lattice points occupied by cations and anions
held together by electrostatic attraction
hard, brittle , high melting point
poor conductor of heat and electricity
COVALENT CRYSTAL
lattice points occupied by atoms
held together by covalent bonds
hard, high melting point
poor conductor of heat and electricity
MOLECULAR CRYSTAL
lattice points occupied by molecules
held together by intermolecular forces
soft, low melting point
poor conductor of heat and electricity
METALLIC CRYSTAL
lattice points occupied by metal atoms
held together by metallic bonds
soft to hard, low to high melting point
good conductor of heat and electricity
