81. Consider a 1.0-L sample of helium gas and a 1.0-L sample of argon gas, both at room temperature and atmospheric pressure. a. Do the atoms in the helium sample have the same average kinetic energy as the atoms in the argon sample? b. Do the atoms in the helium sample have the same average velocity as the atoms in the argon sample? c. Do the argon atoms, because they are more massive, exert a greater pressure on the walls of the container? Explain. d. Which gas sample has the faster rate of effusion?

The Kinetic Molecular model details other aspects of gas particle motion and collisions besides speed. Open the Run Experiment tool under the Experiment tab in the Simulation, and then select the Submicroscopic tab. You can track the motion of an individual gas particle by clicking the Track button in the lower right corner, and you can track a different gas particle by first clicking Pause, then clicking on a gas particle, and finally clicking Resume. Change several of the macroscopic conditions (temperature, pressure, and volume) of the ideal gas and observe how the movement of a tracked gas particle is affected by those changes and collisions. For each condition, make your observations over a consistent amount of time (e.g. 10 s). Then, complete the following statements that describe the atomic behavior of a gas particle. Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer. ▸…
