1. The figure shows a typical Maxwell speed distribution.

How would this distribution change for the same gas, but at higher temperature?

Also, briefly explain where the most probable, average, and root-mean-square speeds would fall on this graph. In particular, try to explain their relative order. (For example, why is the most probable speed less than the average speed?)

2. What's the approximate mean speed of a room temperature hydrogen molecule? At this speed, if the hydrogen molecule didn't run into any other molecules, about how long would it take it to get from one end of your squadron room to the other?

3. The Maxwell velocity distribution is valid

Check the correct answer:
a) for ideal gases
b) for quantum gases
c) for all gases
d) for solids, liquids, and gases
