We start off chapter 20 on the kinetic theory of gases. Today, we derived an expression for the root-mean square velocity of gas molecules wrt temperature, molar mass, and the Boltzman’s constant.

Then we derived an expression for the average kinetic energy of a gas solely in terms of the Boltzman constant and temperature, thereby proving that “temperature is a measure of the average kinetic energy of gas molecules”

Reading assignments were for 20.7 to 20.10
