a shallow bowl, a candle, water, lighter and a large glass jar,
what are the steps?
set your candle on the plate.
pour approx 1/2 to 1 cup of water on the plate.
light the candle, then place the jar upside down over the candle.
take temp readings as the candle burns.
write down your findings.
what happens?
the candle heats the air and expands it. This cancels the depletion of the oxygen temporarily and the water level stays down. When the oxygen is depleted and the candle goes out and the air cools, the volume of the air decreases the the water rises.
what happens (chemical version)
oxygen and paraffin react. The burning produces water and carbon dioxide. For n=1 we balance the equation like this: 202 +CH4 = CO2 + H20. twice as much oxygen is burned than carbon dioxide released, the air volume decreases.
