Rising Water Experiment

This morning we did another experiment, just to start our day. It was called the Rising Water Experiment, well I have seen this type of experiment in social media which I'm already familiar with. So we can be in groups, but we can also work by ourselves. 

Aim: To see what happens to the water revel when the candle is covered 

Hypothesis: Well I already predict that the water will rise, and the fire will go off. I'm actually right because I have seen this experiment before. 

Results: When the experiment is carried out, little bubbles may be seen escaping underneath the glass, indicating that the increased air pressure from the hot air as the candle burns. When the candle runs out of oxygen, it turns out, and the residual air within cools. Cooling air condenses (as seen on a balloon with liquid nitrogen! ), lowering the air pressure within the cup. There was a pressure difference between the air within the cup and the air outside the cup as a result of this. Because of the pressure differential, the high-pressure air outside the cup forced the water down into the plate, allowing the water to be forced upwards into the cup and towards the lower-pressure air within.

Conclusion: Initially, the flame heats the air within the container, and the heated air rapidly expands. Some of the increasing air escapes from underneath the vase, where you may have noticed bubbles. When the flame fades and extinguishes, the air in the container cools, and cooler air contracts, or takes up less space. The candle warms and expands the air. This momentarily offsets the oxygen loss and keeps the water level low. When the oxygen runs gone, the candle burns out and the air cools. The volume of airdrops as the volume of water increases. The short temperature shift causes the water to rise more slowly. Water condensation, as numerous readers have pointed out, should also be noted.

How does it work( summery )

The consumption of oxygen by the flame in the container is a widespread misperception that contributes to the water rising. There is a possible probability of a little rise in the water due to the flame eating up oxygen, but it is incredibly minimal in comparison to the true cause. Simply expressed, when the oxygen was depleted, the water would rise slowly and steadily. Simply expressed, when the oxygen was depleted, the water would rise slowly and steadily. You most likely watched the level increase virtually entirely at once, just after the flame was extinguished. Initially, the flame heats the air within the container, and the heated air rapidly expands. Some of the increasing air escapes from underneath the vase, where you may have noticed bubbles. consumed. When the flame fades and extinguishes, the air in the container cools, and cooler air contracts, or takes up less space. In the container, this contraction generates a weak vacuum – or reduced pressure. It is pressing down on the water in the dish from outside the container. The water stops rising when that pressure equalization is reached. 

I had tons of fun doing this experiment even though I'm by myself, I did it a lot of times. The things you need are Petri Dish, Candle, Lighter, Cup, Water, Matches. 

Convection and Conduction 

Conduction of heat occurs when molecules increase in temperature; they vibrate, and this vibration and movement pass the heat energy to the surrounding molecules. Some examples of conduction of heat are accidentally touching a hot pot, or when a heating pad is applied to you directly and warms your muscles.

Conduction - that is the process by which heat or electricity is directly transmitted through the material of a substance. And when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
