CHE101 - Laboratory Report Title: Charles’s Law Purpose: The purpose of this lab is to view the relationship between the volume and temperature of a gas. In each example of gas, the change in temperature and volume will be measured. Once the temperature of the gas remains constant, the volume can be measured to view the relationship. This relates to Charles’s Law. It states that the volume occupied by a fixed amount of gas is directly proportional to its temperature. My goal for these experiments will be to prove that this law is true. Procedure: 1. Take out a flask and set it on the counter. Close the flask, and then add 1.50 atm of methane to it. The pressure of the flask is now 1.50 atm. 2. After taking the gas syringe and filling it with some of the gas from the flask, the volume of the syringe is 75.0 mL and the flask has a temperature of 294.5 K. 3. The total volume that the gas occupies is 225.0 mL, the volume of the syringe is 75.0 mL, and the temperature is 294.6 K/21.5 C 4. Take out a constant water bath and set it to 0 C. Set the flask onto the bath and wait for the temperature to remain constant. 5. The temperature remains constant at 273.1 K a. Volume of syringe - 58.6 mL b. Total Volume - 208. 6 mL 6. 40 C - 313.1 K a. Volume of syringe - 89.1 mL b. Total Volume - 239. 1mL 7. 60 C - 333.1 K a. Volume of syringe - 104.4 mL b. Total Volume - 254.4 mL 8. 80 C - 353.1 K a. Volume of syringe - 119.7 mL b. Total Volume - 269.7 mL 9. 100 C - 373.1 K a. Volume of syringe - 135.0 mL b. Total Volume - 285 mL Experiment 2: 1. Take out a new flask and set it on the counter. Make sure that the flask is closed. 2. Add 1.50 atm of Butane to the closed flask. The pressure of the flask is now 1.50 atm. The temperature of the flask is 294. 6 K, the volume of the syringe is 75.0 mL, and
the total volume is 225.0 mL.
