Ex 5.1) Which of the following would you predict to best represent the total
pressure of the system Ptot in terms of the pressure of each gas individually (Pred
and Pblue)?
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 the system Ptot
in terms of the pressure of each gas individually (Pred and Pblue)?
Ex 5.3) Rationalise your observations in the previous problem by answering the
following question. If two different gases have the same total kinetic energy
distributed among the molecules and are confined to identical containers, would
you expect a difference in the pressure each gas exerts on the container? Under
what condition(s) would you expect a difference in the distribution of speeds?
