(a) Assuming a Maxwell-Boltzmann velocity distribution, calculate and compare the average speeds for helium and argon atoms at temperatures of 300 K and 3000 K. (b) For a gas with a Maxwell-Boltzmann velocity distribution, the fraction of molecules or atoms with speeds between 0 and V is given by 3/2 2 2 2 2 2 exp 2 2 4 4 exp V V B B m m V F V f V dV V dV k T k T V V V erf V V V Calculate the fraction of molecules that have a speed less than 0.2 V and greater than 2 V for the Maxwell Boltzmann distribution, where V is the average speed. (c) Calculate the mean free path in meters for molecular nitrogen gas at pressures of 0.2 and 2.0 MPa, and temperatures of 100 K and 1000 K. Assume that the hard sphere...
