Experiment 1: Study the Relationship Between Volume and Temperature for a Sample of Air 1. Take a 150 mL Erlenmeyer flask from the Containers shelf and place it on the workbench. Double-click to select the option to close the flask. 2. Take air from the Materials shelf and add 1.25 atm to the flask. 3. Take a gas syringe from the Instruments shelf and attach it to the Erlenmeyer flask. Watch as air from the Erlenmeyer flask fills the gas syringe to equalize the pressure inside to the room air pressure of 1.00 atm. 4. The volume of a 150 mL Erlenmeyer flask is 182.0 mL. Note: The volume of the flask is larger than 150 mL due to the space above the top volume marking. The total gas volume is the sum of the volume of the Erlenmeyer flask plus the volume inside the gas syringe. Double-click on the gas syringe and read the volume. Record the volume of air in the syringe, the total air volume, and the temperature to reference later. - Volume of air in syringe = 45.50 mL - Total air volume = 227.5 mL - Temperature = 21.5 C 5. Take a thermometer from the Instruments shelf and attach it to the Erlenmeyer flask.
