Student Developed Charles’ Law Procedure

The purpose of this laboratory is to investigate the relationship expressed in Charles’ Law. You are to develop a procedure using the following material that will examine the relationship. The procedure should be written in detail in your laboratory notebook.

When designing a procedure for this experiment, it is important to control variables such as pressure and the number of molecules. This is so the volume-temperature relationship can be studied. Here are some questions that will help you get started.

1. What container will hold the molecules?
2. How will the number of gas molecules be held constant?
3. How can the volume of the gas be measured?
4. Recall that the volume of a sphere is V=(4/3) p r ³
5. How will the temperature of the gas be varied?
6. How many volume-temperature measurements should be made?

Your lab procedure should contain a brief statement of the purpose.  It should also contain any preliminary information needed to explain what data you are going to collect as well as how you intend to treat the data.   A sample of your expectations can (should) also be included.  The procedure itself should be very detailed. Finally, there should be a data table ready to be filled in.
