Chemistry Exam 3 Preparation Chapter 7 Learning Objectives Characterize the different states of matter Gas Adopt volume and shape of their container Ideal Gas Law Volume of gas varies inversely with pressure Boyle s Law Volume of gas is directly proportional to temp Charles Law Each component of a gaseous mixture exerts it s own pressure Partial Pressure Molar Concentration Filler Dalton s Law of Partial Pressures Liquid Energy of attraction comparable to thermal energy Maintain volume but adopt shape of container Viscosity is the resistance of liquids to flow Surface Tension is the energy required to increase the surface area of a liquid by a fixed amount Units are in J m2 Increases with increasing intermolecular forces Adhesion and cohesion are present in liquids Surface tension and viscosity come from cohesion which is the force that causes beads of water Shown in Fig 7 12 Solid Shape volume independent of container Strong intermolecular force Describe the behavior of gases The behavior of ideal gases can be explained by the kinetic molecular theory also gases possess weak intermolecular forces Explain the postulates of Kinetic Molecular Theory Define the absolute temperature scale Measure in Kelvin Discuss the meaning of the term thermal energy Thermal energy The average kinetic energy of the molecules in a system is often referred to as the thermal energy the system or the average energy When the thermal energy exceeds the potential energy that holds the molecules in a crystal the crystal melts Thermal energy drives chemical reactions Apply some of the general concepts of KMT to phase equilibria Thermal energy of a system depends on it s temperature Explain the origin of intermolecular forces Exist because there is an attraction between regions of opposite charge on molecules Polarity among molecules leads to molecular dipoles Show how to determine if a molecule has a permanent dipole If the centers of positive and negative charge do not coincide two poles are
