NSET 110

Gases: Properties and Laws

Name: ________________________________________

1. Open the Gas Properties simulation on the University of Colorado’s pHet website: phet.colorado.edu/en/simulation/gas-properties
2. “Pump the Handle” to place gas molecules into the box.
3. Play around with the simulation and list the four things in the simulation you can change below.

1.
2. Using the “Constant Parameter” section to the right of the simulation. Hold first volume constant.  Adjust the amount of gas molecules and the temperature and observe what is happening to the pressure of the system.

1. Repeat the process above with “temperature” held constant.

7. Based on your observations, define the first property of gas molecules- pressure.

8. Repeat Steps 4-6, holding pressure and temperature constant and defining volume.

9. Repeat Steps 4-6, holding pressure and volume constant and defining temperature.

10.How does the amount of gas molecules present affect the three properties above (pressure, volume, temperature)?

11. Using your observations and the simulation, predict the relationship between temperature and pressure (direct proportion or an indirect proportion).

12. Hold volume constant in the “constant parameter” section to the right.

13. Add heat to the system and record your new temperature and pressure in the chart below.

14. Repeat step twelve three more times recording your new temperature and pressure each time.

 Pressure (atm) Temperature (K)

15. Using your observations and the simulation, predict the relationship between volume and pressure (direct proportion or an indirect proportion).

16. Now hold temperature constant.

17. Adjust the volume by moving the man.  Calculate your new volume by clicking on the “Measuring Tools” and checking the “Ruler” and “Layering tool” box.  (Assume the width of the box is 10 nm)

18. Record your new volume and pressure in the chart below.

19. Repeat steps 16-17 three more times.

 Pressure (atm) Volume (nm3)

1. Using your observations and the simulation, predict the relationship between temperature and volume (direct proportion or an indirect proportion).
2. Now hold pressure constant.
3. Choose to either add or remove heat.  Calculate the new volume and record the new temperature and volume in the chart below.
4. Repeat step 21 three more times.

 Volume (nm3) Temperature (K)

1. Using Excel three graphs using the three data tables above.
