Science / Chemistry / Enthalpy Of Sublimation: The change in enthalpy when one mole of solid vaporizes to form one mole of gas. Enthalpies of sublimation are always positive because vaporization involves overcoming most of the intermolecular attra MORE
Science / Chemistry / Antoine Equation: A simple 3-parameter fit to experimental vapor pressures measured over a restricted temperature range: log P = A - . B, T + C, where A, B, and C are 'Antoine coefficients' that vary from substance to MORE
