Candle in Jar
Date: Monday, December 02, 2002
I put a candle in water. The candle was burning. Then I
put a jar over the candle. Then the candle went out and the water in the
jar started to rise.
1.Why did the water rise?
As the air cooled, the pressure dropped on the inside, compared to the
outside of the flask. The water was pushed up from the greater atmospheric
pressure on the outside, to the inside of the flask.
2. Why did it stop at the level where it stopped?
This is temperature dependent of the air on the inside of the flask.
