Compare the properties of liquids and solids with those of the gases; 2. Describe the characteristic movement of the particles of gas, liquid, and solid; and 3. Apply the kinetic molecular theory to describe liquids and solids. LET’S RECALL! What are the three phases of matter? SOLID, LIQUID, AND GAS  VOCABULARY PHASE A UNLOCK! homogeneous, physically distinct, and mechanically separable portion of matter present in a non-homogeneous system.

Solids and liquids are collectively called condensed phases because their particles are in virtual contact. The two states share a little else, however. Kinetic Molecular Theory of Over four hundred years, scientists including Rudolf Clausius and James Clerk L i q u i d s a n d S o l i d Maxwell developed the kinetic-moleculars theory (KMT) of gases, which describes how molecule properties relate to the macroscopic behaviors of an ideal gas. Also known as “Particle Theory” States that “All matter is made up of particles that are always moving. It is useful in describing the properties of solids, liquids, and gases at the molecular level.” Kinetic Molecular Theory of Liquids and Solids Kinetic Molecular Theory of Liquids and Solids Kinetic Molecular Theory of Liquids and Solids Kinetic Molecular Theory of Liquids and Solids Kinetic Molecular Theory of Liquids and Solids Intermolecular Forces of Attraction - The force of attraction by which two atoms or two molecules combine to form a molecule or matter is termed as intermolecular force. - It acts between atom and ions also. The intermolecular force varies for solid, liquid and gaseous matter.  TYPES OF INTERMOLECULAR FORCES OF ATTRACTION : 1.LONDON DESPERSION FORCES 2.DIPOLE-DIPOLE FORCES 3.HYDROGEN BOND 0 LONDON DESPERSION FORCES INSTANTANEOUS DIPOLE 1 A B C D E It is formed as a result from the formation of temporary dipoles, as illustrated for two 0 LONDON DESPERSION FORCES 1 Also called “dispersion force”, are attractions between an instantaneous dipole and an induced dipole. 0 DIPOLE-DIPOLE FORCES 2 0 DIPOLE-DIPOLE FORCES 2 0 DIPOLE-DIPOLE FORCES 2 03 HYDROGEN BOND 03 HYDROGEN BOND THANK YOU FOR LISTENING! “You know it’s right when you feel this undeniable connection and chemistry.” ~ Ali Larter ILLUSTRATIONS
