I need a little help on this problem. Attached is the problem statement...I had just finished typing it out in this box when I accidentally closed the window....didn't wanna type it again cuz its a long statment...(adsbygoogle = window.adsbygoogle || []).push({});

Anyways, for part (a) and (b) I used these two equations:

[tex]v_{rms}=\sqrt{\frac{3K_bT}{m}}[/tex]

and

[tex]T=\frac{mV_{rms}^2}{3k_b}[/tex]

I used the escape velocity of eath to be 11,200 m/s

and get:

T(nitrogen) = 14081.6576275 K

T(hydrogen) = 10057.90411625 K

Then for part (c), I am really unsure on what I am supposed to do...can someone explain to me what is being asked and how to start it. What I have tried is this:

KE = (1/2)m*v^2

I used that to calculate the escape kinetic energy for each nitrogen and hydrogen

Then I used

average translational KE = (3/2) k_b*T

to find the average translational KE of each of the gasses...using their escape temperatures for T

But the KE and avg translational KE for nitrogen is the exact same...and they are the same for hydrogen as well.

I know I am misunderstanding something, can anyone help out? Thanks...
