The International Boiling Point Project

To 13-18 years-old students from The Mathematical Secondary School " Academician Kiril Popov " in Plovdiv conducted the experiment . In the course of three days the students measured the temperature of the Boiling Point .The measurements are showed in charts and tables .

There were three groups of student who worked individually and they gathered their results.
 

We reached these conclusions:

  1. The elevation is the factor which shows the strongest correlation to boiling point.
  2. Other factors like : room temperature , volume and heating devices do not show much correlation to boiling point.
  3. When the water boils there are bubbles which are rising from the bottom of the pot . The pressure is the most important factor which has influence on the bubbles and because of the close bond between the elevation and the pressure the elevation is the most important factor of boiling point.
  4. If we pick a location where the elevation is higher than our location we will predict the pressure will be lower and because of that the boiling point will be lower.
