Inter molecular Forces
Forces between 2 between molecules
Transitions between solid, liquid, and gas
Atom Arrangement Changes
Generally atoms move further going from solid , liquid, gas
Heating Cooling Curves
Temperature graph of a substance as it is heated or cool
Gives the pressure and temperature conditions at which a substance will be at each phase
No attractions molecules glide past each other
Lots of space between molecules
Spontaneous mixing of fluids relative to velocity , diameter and attractive
Gas passes through a small opening
Caused by the collision of gas, molecules, defined as a force per unit area - P= F/A

Crystalline Solids , have a regular patterned arrangement of atoms
Made of ions , positive and negative hold molecules together
Held together by inter molecular forces , lower melting points weaker
Identical atoms grouped atoms grouped together , properties vary widely depending on atoms
Atoms held together in a shared electron sea
Substance with a mixture of elements and metallic properties
Hydrated vs Anhydrous
Some ionic solids attract water so strongly they will bond with CuCI2 and NaOH forming a hydrate like MgSO4 7H2O Epsom Salt
