3. An equation for the average thermal energy per gas molecule (monoatomic or diatomic) is given by Eth = KBT where f is the number of degrees of freedom accessible to the gas molecules. (a) How many degrees of freedom does a diatomic molecule have at low temperatures, medium temperatures, and high temperatures (consult Figure 20.11). (b) Describe what degrees of freedom are accessible (e.g., “translational but nothing else," "translational + vibrational but nothing else," etc.) to the gas molecules in each of three three temperature regions (low, medium and high). Again, the discussion surrounding Figure 20.11 is useful. (c) Is room temperature considered low, medium, or high temperature? Remember, the horizontal scale in Figure 20.11 is logarithmic.
