1. Open Gas Properties and then use the pump to put some of the heavy gas into the box (blue dots). a. Observe gas particles' behavior. b. Pump in some light particles as well (red dots). What similarities and differences do you see between heavy and light particles? c. Hit the orange reset button. Add some heavy gas into the container. Increase the temperature by heating the container. How does the temperature change affect the behavior of the gas particles? d. Now decrease the temperature of the container by cooling it. After reaching 100K, analyze the gas's behavior. How does the temperature change affect the behavior of the gas particles? 2. Reset the simulation by clicking the orange reset button. Add some of the heavy gas into the container. After adding the heavy gas, fill in the blanks below: a. Number of particles in the container (click the particles box to find this): b. Temperature c. Pressure 3. Now decrease the volume of the container by sliding the handle on the left hand side towards the right. Now fill in the current values below: a. Number of particles in the container (click the particles box to find this): b. Temperature c. Pressure 4. How did decreasing the volume affect the pressure of the container? 5. Now add some more particles in the container without resetting. Fill in the values below. a. Number of particles in the container (click the particles box to find this):

b. Temperature c. Pressure 6. How did increasing the number of particles affect the pressure of the container? 7. Reset the simulation by clicking on the orange reset button. Add some of the heavy particles into the container. After adding the particles, click on the Pressure IV Button. After clicking this button, heat the container. How does the volume of the gas change as you increase the temperature? Begin to cool the container. How does the volume of the gas change as you decrease the temperature? Pressure IT After clicking this, move 8. With the gas in the container, click the the wall of the container to the right to decrease the volume of the container. What appeared to happen in order to maintain the same amount of pressure of the container when the volume was decreased? 9. Now move the wall of the container to the left to increase the volume of the container. What appeared to happen in order to maintain the same amount of pressure of the container when the volume was increased? 10. Based on your findings from the simulation, summarize the relationships below for an ideal gas: a. How are pressure and volume related to one other? b. How are pressure and temperature related to one other? c. How are volume and temperature related to each other?
