Final Report
Exercise 1
CHEM 181 DL1 Laboratory Techniques and Measurements
The reason could be atmospheric pressure changes with the higher sea levels, decreasing the degree at which it takes water to boil.
1. Water boils at 100°C at sea level. If the water in this experiment did not boil at 100°C, what could be the reason?
100(102-100)/100=2% error
100(99.2-100)/100=-0.8% error
2. While heating two dif f erent samples of water at sea level, one boils at 102°C and one boils at 99.2°C. Calculate the percent error f or each sample f rom the theoretical 100.0°C.
