Experiment 1: Study the Relationship Between Volume and Temperature for a Sample of Air 1. Took a 150 mL Erlenmeyer flask and closed the flask. 2. Added 1.25 atm of air to the flask. 3. Took a gas syringe and attached it to the Erlenmeyer flask. Watched until the air from the Erlenmeyer flask fills the gas syringe to equalize the pressure inside to the room air pressure of 1.00 atm. 4.Recorded the volume of air in the syringe, the total air volume, and the temperature to reference later. a.The volume of air in the syringe: 45.50 mLb.Total air volume: 182.00 mL + 45.50 mL =227.50 mLc.The temperature to reference later: 21.5°C 5.Took a thermometer and attached it to the Erlenmeyer flask. 6. Took a constant temperature bath and ran the constant temperature bath at 0 °C. 7. Moved the Erlenmeyer flask into the constant temperature bath. Waited until the temperature stabilizes at 0.0 °C. Recorded the volume of air in the syringe, the total air volume, and the temperature.
