And another question. Why do the percentages add up to more than 100%?

I think I see what you mean. You find the number of atoms (for example .036/44 times avagadros number), and then add them all up. That would be the N in the Boltzman-Maxwell equation. And the equation is as follows; N/Z(e^-εj/kt) I have to do that for each one, am I correct? First calculate N...

The trimester is over, and we didn't cover the statistical part of thermo in great detail (as a mater of fact we only began a week or so ago). This is supposed to be a challenge question. Any I thought that maybe as the pressure decreases so would the amount found at that height. But how can you...

Homework Statement Consider the case of a gas in the atmosphere. Assume that the temperature is a constant. Based on the Maxwell Boltzmann distribution, at sea level the atmosphere contains 78.1% N2, 21% O2, 0.9% Argon, and 0.036 CO2. What are the ratios at the the top of Everest? (Molecular...

Thanks for that. But I suppose you can't calculate, seeing as you don't know what N is. I know that because N is big, we can use Sterlings Aprox. but why bother going the extra step? As for the second question, how do you even begin?

Ok I see what you did. I gather from what you said is that I should do the following: N!/(N1!(N-N1)!)=20% (N-N1)!/(N1!(N-N1-N2)!)=40% Right? As for the second one, I have no idea how to approach, but you are right. The probabilities would still have to add to one. I was only...

Here are to challenge questions given to the class to answer to be turned for a free slice of pizza. We have to days, and he said we can get help, and I'm taking him at his word. Here they are. 1). Suppose a room is divided into the front fifth, the middle fifths, and the back two fifths...
