States of Matter, Intermolecular Forces, Gases and Gas laws

States of matter are solid (s), liquid (l), and gas (g)
Phase changes have names: freezing/melting; boiling/condensing
Solid going directly to gas: subliming; example dry ice, CO₂(g)
Forces between particles in decreasing order of strength are: ionic; ion/dipole; hydrogen bonding; dipole/dipole; London (dispersion)
H-bonding only for O…H; N…H; F…H
H-bonding very important in proteins, nucleic acids
The atmosphere: nitrogen, oxygen and 1% argon
Pressure = F/A
Units of pressure can be Pascals (SI); atmospheres (1 atm. = 760 mm Hg = 760 torr)
Kinetic molecular theory models gases as rapidly randomly moving molecules
Ideal gas law (includes other gas laws) PV = nRT; watch for consistency of units.
Molar mass of gas from gas density measurements: PV = (m/M)RT
