Before you begin note the following notes andtips:

You will use 200 units of substance in allactivities.

You can use the ruler to measure volume.

Use tables with proper titles and labels to record yourobservations.

A. In this part you will keep the volume of the container andamount of substance constant and explore the relation betweenpressure and temperature.

Pump 200 units of substance and set the constant parameter toVolume.

Part A:

Add heat to the container. What happens to the temperature?Is this what you expected? Explain.

Add heat 5 times and record the values of temperature andpressure and plot P vs. T. What kind of relation do P and T obey?Find the function.

[TIP: for each of the fives times you add heat, record a fewvalues of temperature and pressure and use the averages in yourplot]

Part B:

Hit the reset button and again pump 200 units of substance.Set the constant parameter to Temperature.

Note: the height and depth of the container remain constantyou can only change its width. Thus, the width of the containercan be used as the volume. Explain why this is the case.

Record the pressure for 5 different values of volume andplot P vs. V. What kind of relation do P and V obey? Find thefunction.

[TIP: For each of the five volumes, record a few values ofpressure and use the averages in your plot]

Part C:

Hit the reset button and again pump 200 units of substance.Set the constant parameter to Pressure.

Record the temperature for 5 different volumes and plot Tvs. V. What kind of relationship do T and V obey? Find thefunction.

[TIP: For each of the five volumes record a few values oftemperature and use the averages in your plot]

Part D:

What are some conclusions you have made?
