hey dear
here is your answer ☞
==============
⭐ procedure :-
1)Pour water onto a plate so that it fills it and add a drop or two of food coloring.
2)Stick a candle into a ball of clay and place it in the middle of your plate
3)You are going to put the cup over the top of the lit candle, make a hypothesis/guess about what you think will happen
4)Light the candle
5)Put the cup over the candle
You will see the candle slowly extinguish and then the water will creep up into the cup. Pretty amazing! The hot air caused by the candles pushes air out from under the cup (hot air expands and causes bubbles at the bottom). As soon as the candle goes out, the air cools and condenses, but now there is less air in the cup than when it started. This is low pressure. we know, The outside air (high pressure) wants to push into the cup (low pressure). ⭐
hope it helps ^_^
