8.103

Postby Kaylin Krahn 1I » Fri Mar 16, 2018 1:16 pm

Are we supposed to know that average kinetic energy is equal to (3/2)RT? Overall, how does the solution manual obtain these answers and are we expected to know this formula even though it's not given on the sheet?

I think it actually is given on the eqn sheet if you're referring to the ideal gas U.. its on the one in the course reader

(3/2)*R deals with an ideal gas at a constant volume

That equation, I believe, is given on the equation sheet. Or at least U = (3/2)nRT is given. As for the KEavg=3RT/2, I believe that's in the book and may just be something that needs to be memorized.
