Boyle’s law
volume of gas varies inversely with pressure, PV=k(n,T)
K
C+273.15
Charles’ law
volume of gas is directly proportional to temperature (in K), V=k(n,P)T
avogadro’s law
volume at constant T&P is directly proportional to n, V=k(P,T)n
ideal gas law
PV=nRT
thermal energy
RT
intramolecular forces
within a molecule
intermolecular forces
between molecules
dispersion forces
present in all molecules because of induced dipoles, increase with size/mass
dipole-dipole forces
present in polar molecules because of permanent dipole, the more polar, the stronger the force
hydrogen bonding
N-H, O-H, F-H, strongest bond
viscosity
resistance of liquids to flow
heat of fusion
heat required to melt a substance at its melting point
heat of vaporization
liquid to vapor
deposition
vapor to solid
sublimation
solid to vapor
