Review of Lecture 24: The practical questionhow do we count gas molecules? In gases, we require P, V and T measurements. Gas laws tell us how they relate to numbers. Kinetic theory says molecules are always in motion. In gases, the temperature is proportional to the average kinetic energy of the gas molecules. Light molecules move faster; heavy, more slowly; important velocity parameters vary as T½. M. Transport depends on the speed of gas molecules. Pressure is the result of collisions between gas molecules and the walls of the container Reading: Chapter 15 Hmwk #11 due November 27
