Question

5.82 The temperature in the stratosphere is -23 C Calculate the root-mean-square speeds of N O and O, molecules in this region. The average distance traveled by a molecule be- tween successive collisions is called mean free path. For a given amount of a gas, how does the mean free path of a gas depend on (a) density, (b) tem- perature at constant volume, (c) pressure at constant temperature, (d) volume at constant temperature. and (e) size of the atoms? 5.83
