Lab Report
The Lab Report is a summary of the experiment’s questions, diagrams if needed, and data tables. You need to fill in this document and submit via the Blackboard link in your experiment module. Lab Report is worth 35 pts. Be careful of Significant Figures.

Questions (Each question is worth 1 pt)
- 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?
- While heating two different samples of water at sea level, one boils at 102°C and one boils at 99.2oC. Calculate the percent error for each sample from the theoretical 100.0°C.
Exercise 2: Volume and Density
