Experiment 1:

Results

1. Recording the data pairs of temperature and volume:

Volume(mL) ...........Temperature(°C)

75.......................... 21.50

58.6....................... 0.000

88.5........................ 40.00

104.4.................... 60.00

119.7..................... 80.00

135.0.................... 100.0

2 Prepare a graph of the data, with temperature (in Kelvin) on the X-axis and volume (mL) on the Y-axis. Draw a straight line through the data points.

3 Draw a straight line through the data points.

4 Does your experimental data verify Charles' Law?

5 What volume would the gas sample occupy at 50C, and at 120C?

. 6 List two sources of possible error if you had done activity in the real lab.
