What is the correct explanation of what happens to the water when the candle inside the beaker burns out?

What actually happens? The evaporation of the water to water vapor as the candle burns, and the cooling that occurs when the candle goes out, cause lower air pressure inside the glass than outside. The water is pushed into the glass until equilibrium is reached.)

Why does water rise in a jar with a candle?

Because twice as much oxygen is burned than carbon dioxide released, the air volume decreases. This cancels the depletion of the oxygen temporarily and the water level stays down. When the oxygen is depleted, the candle goes out and the air cools. The volume of the air decreases and the water rises.

What happens when a candle burns in water?

The burning candle produces carbon dioxide and water in the form of water vapor. The glass becomes foggy due to this water.

Why do you put a candle in water?

A floating candle is a candle that when placed in water displaces more water by weight than the weight of the candle. So when it’s placed in water it floats! Votive or Pillar candles would not be able to float even though they displace water because they are top heavy, so they would tip into the water.

Why do candle not burn in inverted glass?

If you limit the amount of air available, the candle’s flame eventually goes out once it uses up all the oxygen.. Thus, oxygen inside the glass jar will decrease and it gets filled with carbon dioxide, and eventually the candle’s flame will Extinguish.

Why is the candle flame extinguished after a few seconds?

Carbon dioxide molecules are heavier than air. Because of this, they push the oxygen and other molecules in the air out of the way as they sink down over the flame and candle. When oxygen is pushed away from the wick, it can’t react with the wax anymore. This makes the flame go out.

How does the candle trick work?

In a trick candle, magnesium powder is incorporated into the candle’s wick. When the flame is blown out, the hot embers from the wick ignite the magnesium powder, producing tiny sparks. This, in turn, ignites the vaporized paraffin hydrocarbons, which relights the wick.

What happens when you cover the candle with the glass jar?

What will happen if a burning candle is covered with a glass jar? Oxygen is the fuel for wax and makes the wick burn. When the candle is closed with the glass jar the oxygen supply is stopped. Initially, the candle burns by making use of the oxygen within the glass and slowly when there is no oxygen the flame goes off.

What happen when you cover the candle with the glass jar?

Can you put water in a candle?

The National Candle Association recommends using a candle snuffer or some sort of lid to extinguish a candle. The organization says using water can cause hot wax to splatter, which is one way an explosion can occur.

Why did the candles stop burning when the students placed glass jars over them?

Why did the candles stop burning when the students placed glass jars over them? The jars prevent oxygen in the surrounding air from reaching the flames, so the flames go out.
