EXPERIMENT 1: CHARLES’ LAW

In this experiment, you will explore the relationship between temperature and volume, and connect this to Charles’ Law.

PROCEDURE

1. Fill the syringe halfway with air, and seal the syringe by screwing the cap on. Record the volume (mL) of gas in the cylinder in Table 1 on the Experiment 1 Data Sheet.

2. Using a timer, hold the top of the thermometer up in the air for 30 seconds. Record the temperature of the room in Table 1 on the Data Sheet.

3. Fill one Styrofoam® cup with hot tap water. Place the thermometer in the cup.

LAB SAFETY: Avoid using extremely hot water. Handle hot water carefully.

4. Fully submerge and hold the air-filled syringe in the hot water for 30 seconds. Use the timer to monitor time.

5. Gently push the piston down until the plunger cannot move any farther. Observe the new volume inside of the syringe. Record this volume and the water temperature in Table 1 on the Data Sheet.

6. Prepare a cup of water mixed with ice. Repeat Steps 4 and 5 for the cold water bath. Record the volume and temperature in Table 1 on the Data Sheet.

7. Convert all measured temperatures from degrees Celsius to Kelvin, and record your results in Table 1 on the Data Sheet. When you’re done, take a picture of your completed lab set up. Remember to include your name and lab access code handwritten in the background of the photo.
