2. THE INTERNATIONAL BOILING POINT PROJECT BOIL, BOIL, TOIL AND TROUBLE

3. OBJECTIVE Through collaboration and experimentation, students will discover whether there is a correlation between the boiling point of water and the elevation at which water is boiled, the room temperature where water is boiled, or the heating device used to boil water.

4. HYPOTHESIS If the room temperature increases, then the boiling point of water will occur faster.

5. PROJECT PURPOSE What Happens When Water Boils? As water boils, the water turns into steam. First the water begins to form bubbles at the bottom of the beaker. Then the bubbles begin to rise and pop off the surface, evaporating into the air. Energy is used to transform the water from its liquid to its gaseous state. This is the BOILING POINT of water.

6. PROJECT PURPOSE What Factor Has the Greatest Effect on the Boiling Point? Data was recorded to determine if the volume of water, elevation, heating device, or room temperature has the greatest effect on the Boiling Point of water.

7. THE EXPERIMENT LOG Room Temperature: 22 degrees Celsius Elevation: 21 meters Amount of Water: 300 milliliters Heating Device: Bunsen Burner

8. RESULTS BOILING POINT 102.5 degrees Celsius International Boiling Point Project International Boiling Point Project

9. ANALYZING THE DATA Room Temperature / Boiling Point

10. ANALYZING THE DATA Elevation / Boiling Point

11. ANALYZING THE DATA Volume of Water / Boiling Point

12. ANALYZING THE DATA Heating Device / Boiling Point

13. CONCLUSION The purpose of this investigation was to determine which factor had the greatest effect on the boiling point of water. The major finding from this experiment was that elevation had the greatest effect. The hypothesis “If the room temperature increases, then the boiling point will occur faster,” was not supported by the data.

14. CONCLUSION A recommendation for further study would be to determine if there is any correlation between boiling point and air pressure.
