Phys. 369, Fall 2009 Homework #11 Due Mon. Nov. 30, beginning of class 100 points total 1. (22 points) Suppose that you have a container of pure nitrogen gas at pressure 0.5 atm and temperature 200 C ° . Suppose that the nitrogen molecules collide as hard spheres with a radius of 10 1.88 10 m. × Calculate each of the following quantities: a) the mean free path of a molecule. b) the average rate at which a given molecule will collide with other molecules. c) the thermal conductivity of the gas. d) the viscosity of the gas e) Suppose that you are able to follow the motion of a specific nitrogen molecule. (For example, it might be a different isotope with a slightly shifted spectral line that you could excite selectively.) If you take the origin of coordinates to be the position of the nitrogen molecule at time 0, t = about how long would it take for the rms displacement of that molecule to reach a value of 10 cm by diffusion through the gas?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
