How Does Temperature Affect The Burning Time Of A Candle

I. Introduction
Background Research Most of the people die because of suffocation during fire incidents. Many people in the world also get respiratory problems because of insufficient supply of air or ventilation in their houses. During fire incidents, many people die because they sometimes inhale carbon monoxide that is poisonous for a human body. That is also a good way to find out if a person was alive or dead by the time the fire got to them; if they were dead before the fire got to them, they would not have certain inhalation burns or carbon monoxide (CO) in their blood.

Research Problem What is the effect of the length of the candle with insufficient supply of air to the time of burning up of the candle?

III. Hypothesis The greater the length of the candle, the greater the burning time of the candle.

IV. Experimentation
Materials and Procedure
3 similar candles with different length
3 jars with same size
Match
Ruler
Timer

We made 3 set-ups for this experiment. Each setups has different length of the candle (Setup A has 2.5 cm, Setup B has 3.9 cm, Setup C has 4.8 cm). After that we lighted the candles, then we covered each of them with same size of jars. We waited for the fire in the candles to fade, and then we used a timer to record the burning time of each candle.
