AP Chemistry Chapter 13 Outline Condensed phases: the liquid and solid phases; phases in which particles interact strongly. 13.1 Gas condensed when cooled and compressed. In the liquid state the forces of attraction among particles are great enough that disordered clustering occurs. It is hard to compress a liquid. Liquids diffuse into other liquids with which they are misicible. The natural diffusion rate is slow at normal temperatures. Cooling a liquid lowers its molecular kinetic energy
