Question 2 of 12
2. Question
For the same conditions of Figure 7, Figure 13 shows the same P, V, N, and T but this time for light particles (i.e., orange balls). Find urms for the light particles. Based on Eq. (2) above will new urms be higher or lower than that shown for heavy particles (blue balls)? Justify your answer in light of Eq. (2) above.

Question 3 of 12
3. Question
Carry out the mixing process of two gases starting with the initial conditions given in Figure 14. Remove the divider and allow a sufficient time to reach equilibrium both thermally and chemically (i.e., composition). Describe the final equilibrium condition in terms of number of balls or particles as divided or distributed throughout the entire big chamber.
