TI-92 CAS Window -- Boyle's Law

Ideally you should use your own data. However, you can use some data that we collected by clicking here, downloading the program boyledat in the usual way, and then running the program by typing boyledat() and then ENTER from the home screen. This puts the data into two lists -- L1 for the volume and L2 for the pressure, just as if you had collected your own data.

Looking at this data graphically requires several steps.

• Make sure the TI-92 graphics mode is set to FUNCTION. Note: You may want to refer to the TI-92 help module Graphing a Function for this module.

• Set up the WINDOW screen as shown in the screen below

  

• Go to the Y= screen and arrow up to highlight Plot 1: as shown in the screen below.

  

• Press ENTER and then set up the Plot 1 screen as shown below.

  

• Now press GRAPH to see the screen below.

  

• Next we want to compare the data with the function
  Pressure = 20 * 0.336 / volume

  Enter this function into the Y= screen as shown in the screen below.

  

• and then press GRAPH to see the screen below.

  

Notice how well the curve fits the data.
