So in this question, we have a one simple of helium gas in a one leader sample of argon gas. Um, there at the same temperature and same atmospheric pressure on, we're going to answer a few questions about them. So the 1st 1 a is do the atoms in the helium sample have the same average kinetic energy ISS, Adams and Argon sample the answer that is actually yes, on the reason weaken kind of explain. That is because average kinetic energy has nothing to do with the actual identity of the molecules. In fact, we have this equation written down where we have the average kinetic energy just three halves times our teeth, uh, considering are is constant for all gases and t It says that the problem is the same for both these gases. You'd expect both samples of the same kinetic energy average kinetic energy. All right, moving on to part B. Ah, and asks, Do the atoms in the helium sample have the same average velocity? Now, the answer that one is going to be no on the reason for that is we know that kinetic energy ah is equal to 1/2 m b. squared, so we know they have the same average kinetic energy. But we also know that organ is a lot heavier. Eso therefore, helium has a have a higher velocity in order to account for that fact for C um, it asks. Since the organ atoms are bigger, do they exert more pressure on the walls of the container? The answer this one again is no on. We can explain this using the ideal gas law, right? So I can say that PV physical to end our teeth, right, if I want to. Aiken kind of rearrange this a little bit ready as p equals and times are t over v all right. So, as we can tell, P and N are directly proportional. So as an increases, so will Pete and as and decreases so peak. Therefore, we can kind of partially that the pressure is not a result of the size of the particles per se, but more over the number of particles that are present and, uh, moving on. Lastly to d, it asks which gas has the faster rate of infusion eso as a general rule. The smaller the molecule it is, the faster it moves So in this case, the answer is going to be helium on. If we need a more mathematical explanation, we go to Graham's law, which is that the rate of effusion is proportional to one over the square of the molar mass, which means that as Mullah Mass increases, the rate of infusion will decrease.
