Chapter 11 Liquids and Intermolecular Forces

Chapter 11 Liquids and Intermolecular Forces. States of Matter. The fundamental difference between states of matter is the distance between particles. States of Matter. Because in the solid and liquid states particles are closer together, we refer to them as condensed phases.
