Charles’ Law
Objectiveto understand Charles’ Law and the direct relationship between
temperature and volume.
Materials-
(1) Syringe
(1) Thermometer
(1) Bunsen Burner
(1) Ring Stand
(1) Wire Gauze
(2) 250-mL Beakers
(1) 500-mL Beakers
(1) Flint Sparker
(1) Iron Ring
(1) Beaker Tongs
Procedure1. Set the syringe to 20mL, seal it and record the volume and temperature of the room.
2. Heat up approximately 200 ml of water in the 250-mL beaker and bring to a boil.
3. Insert the sealed syringe into the boiling water for 2 minutes and record the volume
along with the temperature of the water.
4. In the 500 ml-beaker, add approximately 100mL of water and a handful of ice. After
about 2 minutes place the sealed syringe in the ice water bath. Record the volume of the
syringe and the temperature of the ice water bath.
5. Insert the syringe into the dry ice/acetone bath (temp –77oC) and record the volume.
6. Plot a graph of volume vs. temperature, and extrapolate (extend) the best fit line to a
volume of zero.

Volume
Questions1. Calculate the volume of a gas at constant pressure at 200oC that occupies a volume of
200mL at 300C.
2. Calculate the temperature of a gas at constant pressure that has a volume of 500mL
that occupies a volume of 250mL at 300C.
3. Calculate your % error give the actual absolute zero is –273oC.
