Document Summary
Solid: (shape) constant [rigid & fixed], well defined shape (vol) definite & constant (particulate movement) particles lie close tgt, arranged @ regular 3d form, vibration @ fixed position, closely bonded. Amorphous solid - x ordered struc e. g. plastic, glass. Crystalline solid - ordered struc e. g. salt, diamond. Liquid: (shape) variable, same as bottom of container (vol) definite & constant (particulate movement) randomly move beneath surface, particles are close tgt w/ loose interaction between them, limited to vol of liquid & shape of bottom of container. Strength of attraction between particles of subs determine its state -> @ rm temp: moderate-strong forces = (l)/(s) -> stronger force = higher (l) bp/ (s) mp. Intermolecular attraction cuz attractive forces between opp charges e. g. 1. +ve end of polar molecules to -ve end of polar molecules (h bond esp strong) 3. Boil (l) = overcome attractions between particles x break covalent bonds.
