In this Chemistry topic you will advance your critical thinking by focusing on forces and matter starting with our lesson, Summary: Types of Intermolecular Forces. The types of Intermolecular Forces and States of Matter that are present in a substance are determined by different temperatures. In order to drink water to quench our thirst, it must be in liquid form. In order to breathe the oxygen we need to live, it must be present as a gas. Learn to apply your comprehension of critical concepts found in Dipole-Dipole Force Definition and London Dispersion Force Definition. As you study Intermolecular Forces and States of Matter, you will learn to identify the three types of intermolecular forces and how they determine whether a substance is a Solid, Liquid or Gas at room temperature. From Phase Diagrams to Enthalpy Calculation, you will become proficient in the applications, methods and calculations presented in our Intermolecular Forces and States of Matter topic.
