【答案】Today,we carried out an interesting experiment.Before we started,we prepared a candle,a glass that is a little higher than the candle,a basin and some water.
First,the candle was placed at the bottom of the basin and some water was poured into the basin.Then we lit the candle and covered it with the glass that was full of air.We waited until the candle went out.
To our astonishment,we saw that the water level in the glass was higher than that in the basin.We draw the conclusion that the difference in air pressure inside and outside the glass plays a major role as to why the water level changes.
