Background Information
Step by Step Process
You need to prepare 3 different temperatures of water, prepare an ice-water bath, a room water bath, and also a hot water bath. Next you will need to get the Temperature Probe and Gas Pressure Sensor prepared for the experiment. Prepare the computer for data collection by opening the file “07 Pressure-Temperature” from the Chemistry with Computers folder of Logger Pro. Click collect to begin data collection. Collect pressure vs. temperature data for your gas sample: First collect data from the cold water and its pressure and do that for the other ones too. Click stop when you have finished collecting data. Turn off the hot plate. Record the pressure and temperature values in your data table, or, if directed by your instructor, print a copy of the table. After you get all your data collected, you must then input a best fit line into your graph to find the constant.
