Ch Liquids & Solids III. Changes of State (p )
A. Phase Changes Evaporation Evaporation molecules at the surface gain enough energy to overcome IMF Volatility Volatility measure of evaporation rate depends on temp & IMF
A. Phase Changes Equilibrium Equilibrium trapped molecules reach a balance between evaporation & condensation
A. Phase Changes Vapor Pressure Vapor Pressure pressure of vapor above a liquid at equilibrium IMFv.p.tempv.p. depends on temp & IMF directly related to volatility p.478 temp v.p.
A. Phase Changes Boiling Point temp at which v.p. of liquid equals external pressure IMFb.p.P atm b.p. depends on P atm & IMF Normal B.P. - b.p. at 1 atm
Which has a higher m.p.? polar or nonpolar? covalent or ionic? A. Phase Changes Melting Point equal to freezing point polar ionic IMFm.p.
A. Phase Changes Sublimation solid gas v.p. of solid equals external pressure EX: dry ice, mothballs, solid air fresheners
Changes in State. Solid to a Liquid Melting. – Where a solid changes to a liquid. – Particles must gain energy and become free to move around. Melting.

Changes of State Beta Science Overview This PowerPoint examines how matter changes from state to state. Changes in state are explained in terms of matter.
Kinetic Energy and Phase Changes. Diffusion Diffusion is the process by which molecules will move randomly in order to fill the space that they are in.
E. Changes in State (phase changes) 1. Melting - solid to liquid a. Particles get more kinetic energy and begin rotating around each other. b. There isnt.
Phase Changes Courtesy CA Standards Students know energy is released when a material condenses or freezes and is absorbed when a material.
