Chemistry Unit V Objectives Chapter 14 I.     Describe the Kinetic-Molecular Theory and explain how it accounts for behaviors of gases.   II.    Explain how pressure is measured with a manometer, and barometer and know the conversions for pressure units: 1 atm = 760 torr (mm Hg) = 14.7 psi = 101 325 Pa 1 bar = 100 000 Pa = 100 kPa = .9869 atm Memorize STP III.      Know the equations for Boyle’s Law, Charles’ Law, Gay-Lussac’s Law, Dalton’s Law of Partial Pressures, and the Combined Gas Law. Use the gas laws to solve problems involving pressure, temperature, and volume of gases.

Chem Unit V Objectives Chapter 14 cont… IV.    Recognize and be able to graph inversely and directly proportional relationships for pressure, volume, and temperature of gases.   V.    Compare the relative rates of diffusion of gases using Grahm’s Law of diffusion. VI.    Use the equation pv = nRTk to solve Ideal gas problems that include number of moles (n) and the gas constant (R) R =.0821 atm-L/mol-K = 8.314 Pa-m3/mol-K = 8.314 J/mol-K VII.   Compare ideal and real gases and explain them in terms of kinetic molecular theory. Relate gas density to temperature and molar mass.
