Data Collection With the Simulation


Now you will acquire data and create a graph using the same simulation integrated with an online data analysis platform called CODAP. Below, you will see a CODAP workbench. CODAP will allow us to visualize our data immediately upon entering it into the platform.

Let's begin with familiarizing ourselves with the CODAP environment:

  1. The platform is below these instructions. Notice the starting volume at room temperature of 23°C has been entered for you.
  2. Adjust the slider bar labeled "gas-temperature" to a temperature other than the starting temperature.
  3. Begin the simulation by hitting "setup" and then “go/stop”.
  4. Allow the simulation to run for 100 ticks before pressing the "record-data" button. Notice that your data will appear in both the data table as well as create a data point on the graph at right.
  5. Record volume measurements at 3 additional temperatures (for a total of 4 temperatures as 23°C has been entered for you), waiting 100 ticks after changing the temperature to click "record-data" (one should be the minimum temperature and one should be the maximum temperature on the gas temperature slider bar).
  6. Observe the resulting plot. Then answer the questions below the CODAP workbench.


Questions

Please answer the questions below.

How does changing the temperature of a gas affect the volume of that gas?


Describe the appearance of the graph you created in CODAP.
