1. Consider the root-mean-square speed of H2 at room temperature
Consider the root-mean-square speed of H2 at room temperature. What do you think is its order of magnitude?
10 m/s
102 m/s
103 m/s
104 m/s

2. Consider the root-mean-square speed of H2 at room temperature
Consider the root-mean-square speed of H2 at room temperature. What do you think is its order of magnitude?
10 m/s
102 m/s
103 m/s
104 m/s
The exact value is 1927 m/s (see notes and textbook).

3. Consider an empty container into which you inject molecules that
all have exactly the same speed. Assume that all collisions with the
container walls are elastic, but they do not interact with each other.
Will they retain their speeds?
Yes No
