Calculate the root mean square fluctuation of the kinetic energy of a monatomic ideal gas about its mean value (3/

2)NkT, N being the number of molecules. [Hint: urms = [<u^2> - <u>^2]^(1/2) and <u>= (3/2)kT. Also need math handbooks for integrals and the

Gamma function.]

If anyone can solve this and reply the solution within two days I would be ever grateful!!!
