6. The four most common gases in the atmosphere are N2, O2, Ar, and CO2 a. Which gas has the highest average kinetic energy at room temperature? N2/02/ Ar/ CO2/all have the same KE (circle one) b. Which has the highest average velocity? Nz/ 02/ Ar / CO2 / all have the same average velocity (circle one) Assuming all gases are in containers of equal size, temperature, and pressure, which gas has the highest density? c. N/ 02 / Ar / CO, / all have the same density (circle one) 7. A sealed container contains equal amounts of the following volatile components: diethyl ether- C4Hio0 menthol-C10H200 Assuming your sense of smell is equally sensitive to both, and you were 20m away when the container is opened, which would you smell first? Diethyl ether/menthol /you would smell both at the same time A container with equal amounts of CO2 and Ar springs a small leak. If the rate of CoO escaping is measured at 2.0 mL/min, what would you predict for Ar? 8.
