Well the thing is I don't know. Because I cant find it no where in my book about the gaes and what they contain. This is a ezam study quiz and I am lost. have no idea what it is even talking about.

Still no help, i just read about the kinetic energy section agian and I am still lost??

How does the average kinetic energies per molecule compare in a mixture of hydrogen and nitrogen gases at the same temperature? Really, I have read this stupid textbook 6 times. No explanation of this question no where. Please help!!!!
