Hi, we did this experiment as an introduction to pressure where you stand a candle on top of a small puddle of water on the bottom of a plate. You then put a glass jar over it and when the candle burns out the water level goes up inside the jar. I found this which shows the experiment if I haven't described it properly:
We were told that the candle burns the oxgyen in the glass jar and this is why it rises. However after reading I found contradicting sources e.g. http://www.stevespanglerscience.com/lab/experiments/why-does-the-water-rise/. Where it says that this line of thinking is a common misconception. Please could someone explain the correct way? Thanks.
