Mathematical Relationship Between Burning Time and Volume of Air Purpose: To determine the graphical and mathematical relationship between the volume of air available to a burning candle and the time for it to extinguish. Materials:

50 ml Beaker600 ml Beaker
100 ml Beaker1000 ml Beaker
250 ml BeakerCandle
400 ml BeakerStopwatch
Matches
Procedure:
1. Goggles were acquired from the goggle cabinet.
2. The candle was lit and as I placed the 50 ml beaker over the candle, my partner started the stopwatch to record how long the candle burned under the beaker. 3. When the flame extinguished, I recorded how long the flame lasted under the 50 ml beaker. 4. Steps 2 & 3 were repeated for each size of beaker. Safety:

* Standard lab attire is acquired, including safety goggles. * Take care when working with glass
* Take care when working with a lit candle
Data:
50 ml Beaker (seconds)| 100 ml Beaker (seconds)| 250 ml Beaker (seconds)| 400 ml Beaker (seconds)| 600 ml Beaker (seconds)| 1000 ml Beaker (seconds)| 1.42| 2.98| 7.36| 9.32| 14.76| 23.62|

Calculations and Analysis:
A graph of the data is provided on a separate sheet. The graph was produced with beaker size (in ml) on the x-axis and time the flame survived (in seconds) on the y-axis. Conclusion:
This experiment was intended to determine the graphical and mathematical relationship between the volume of air available to a burning candle and the time for it to extinguish. It was found hat the graph of data was a straight line, indicating that the relationship between the volume of air available to a burning candle and the time for it to extinguish are in direct correlation.

Wolfram Alpha says that the more air a flame has, the longer it will burn. Therefore, we expected the flame to last longer in the larger beakers. The points in our graph stayed fairly close to our trend line....
