Measuring Data
uThe water temperature is displayed on the calculator.
uRead the volume of the gas using the markings on the syringe and read temperature at that time, which is displayed on the calculator.

uAdd a little of the cold water to the water in the container, and mix. After waiting a few minutes, take readings of the volume and temperature.
uRepeat this step until the temperature of the water in the container approaches the temperature of the cold water.

2Mixing Stick
uRepeat the above steps, adding ice instead of cold water and taking readings.

uGraph the readings, which produces a graph that is virtually linear.
uSubstitute two of the values on the graph into the expression, and calculate the temperature where volume becomes zero.
V = | V1 – V0 T + V0 | T = – | V0T1 |

Should the plastic container become too full during the above steps, it is all right to remove some of the water. However, make sure that the syringe remains under the surface of the water.
