3 Gases On a Graph, Which is True ?? 1. The problem statement, all variables and given/known data http://img103.imageshack.us/img103/9302/spdistus8.jpg [Broken] Based on the distributions show above, which statements for the three gasses I II and III are true? Note that the temperature is constant for all three. a) Gas III is the heaviest of the three gasses. b) The most probable speed of the molecules of gas II is greater than that of the molecules of gas I. c) All the molecules of gas III have an actual speed that is greater than those of gas I. d) The average kinetic energies of the three gasses would be different. e) Increasing the temperature would increase the most probable speed of the molecules of each gas. 2. Relevant equations Knowing About Gases. 3. The attempt at a solution For A: I got False because on a graph My Professor showed in class he had the example of Curve I as O2 and Curve III as He.. and obviously He is the smallest. For B: The most probable speed is at the peak so obviously Molecule II isn't as high as molecule I so that is False. For C: All of Gas III Speed Are NOT always greater then the speeds of Gas I so False For D: I got True because the Formula makes them all dependent on their mass. *EDIT* This is True Because the Temp is Constant. For E: I got False, because when you increase the temp is doesn't move the peak of the curves. I need Help, Please :) Thank You.
