Ex. 5.2 Click the 'Show Total Pressure' toggle to plot (in black) the total pressure of the system. After observing the total pressure of the system, which of the following would you predict to best represent the total pressure of the system Pot in terms of the pressure of each gas individually (Pred, Palue)? (a) Ptot = Pred + Polue (b) Ptot = Pred X Polue Peed %3D (c) Pot %3D Pue Pred - Polue (d) Ptot = Ex. 5.3 Rationalize your observations in Ex. 5.2 by answering the following question: if two different gases have the same total kinetic energy distributed among the molecules and both gases are confined to identical containers, would you expect a difference in the pressure each gas exerts on the container? Choose the answer with the best explanation. HINT: use Eq. (2) (a) There will not be a difference in pressure. Heavier gases will be moving faster, but when the molecules impact the side of the container, their increased mass will compensate for their smaller velocity and the pressure will remain constant. (b) There will not be a difference in pressure. Heavier gases will be moving slower, but when the molecules impact the side of the container, their increased mass will compensate for their smaller velocity and the pressure will remain constant. (c) There will be a difference in pressure. Heavier gases will be moving faster and when the molecules impact the side of the container, their increased speed will result in a greater force of impact and hence a greater pressure. (d) There will be a difference in pressure. Heavier gases will be moving slower and when the molecules impact the side of the container, their decreased speed will result in a smaller force of impact and hence a lower pressure.
