Vapor Pressure The molecules at the surface can spontaneously go into a gas as KE increases enough to break attractive forces.

The phase of a substance depends upon two parameters: Temperature Pressure Gives the particles more energy to overcome attractive forces. Raises the vapor.

Phase Diagram Vocabulary Triple Point: Only point at which all three phases (solid, liquid, gas) exist at equilibrium Critical Point: Point at which no amount of pressure can turn a gas into a liquid. Phase Boundries: Line along which 2 phases exist at equilibrium.

Phase Diagram Vocabulary Standard Melting Point: Temperature at which a substance exists in solid/liquid equilibrium when at (1 atm) standard pressure Standard Boiling Point: Temperature at which a substance exists in liquid/gas equilibrium when at (1 atm) standard pressure Not all substances have standard boiling and melting points.
