TermDefinition
Phase Diagram A graph of pressure and temperature that shows the conditions under which a substance exists.
STP Standard Temperature and Pressure
Triple Point The temperature and pressure at which the solid, liquid, and gas phases co-exists.
Critical Point Where substance indicates the critical temperature and critical pressure.
Molar Enthalpy of Fusion The amount of energy required to melt one mole of a solid
Nonvolatile Liquids that do not evaporate readily because of strong attractive forces between particles.
Deposition The change of a gas directly to a solid.
Sublimation The change of a solid directly to a gas
Kinetic molecular theory Particles are in constant motion
Molar Enthalpy of Vaporization The amount of energy as heat needed to vaporize one mole of a liquid
∆H enthalpy of products - enthalpy of reactants
Hess' Law Overall enthalpy change in a reaction is equal to the sum of the enthalpy changes for the individual steps in the process.
Endothermic Heat energy is absorbed; products higher
Exothermic Heat energy released; products lower
Enthalpy Change using Hess' law; process equals the sum of the energy difference of products minus the sum of the energy difference of the reactants
