PHASES OF MATTER

3+1 States of Matter: [blank_start]SOLIDS[blank_end]: definite shape, definite volume [blank_start]LIQUIDS[blank_end]: indefinite shape, definite volume [blank_start]GASSES[blank_end]: indefinite shape, indefinite volume

3+1 State of Matter: PLASMA - Positive sea of electrons and disassociated sea of nuclei - Produce electric currents and magnetic fields and conduct electricity

Plasma is formed when gasses are iodized when exposed to extremely high temperatures/strong electric voltage diff.

[blank_start]Intermolecular Forces of Attraction[blank_end] (IMFA) - forces of attraction that exist b/w molecules of matter

IMFA in solids are stronger than liquids

- Occurs between neutral polar molecules - A separation of charge causes the negative ends of molecules attract the + ends of other molecules

- v weak interactions - occur in all molecules - most important in the bonding b/w nonpolar fat molecules and hydrocarbons - strength of dispersion forces increases w/ molecular weight

- strong type of dipole-dipole interaction - involves a dipole consisting of a hydrogen atom and a v electromagnetic atom (N, O, or F) - strength increases as the electronegativity of the atom bonded to H increases
