When a candle is covered by a beaker, the flame consumes the available oxygen in the container, leading to the flame going out due to lack of oxygen necessary for combustion. Without oxygen, the candle flame can no longer sustain itself and will extinguish.

Why do candles go out when you put a beaker over it?
When you place a beaker over a candle, you are cutting off the oxygen supply needed for the candle to burn. The flame requires oxygen in order to continue combustion, and by placing a beaker over it, you are essentially smothering the flame until it goes out.
What happens to the flame of the candle after it was covered by the beaker?
When a candle flame is covered by a beaker, it consumes the available oxygen inside the beaker until it is exhausted. Once the oxygen is depleted, the flame will go out due to the lack of oxygen needed for combustion.
Why does a lit candle go out when a inverted beaker is on it?
When an inverted beaker is placed over a lit candle, the flame goes out due to lack of oxygen. As the candle burns, it consumes oxygen and generates carbon dioxide and water vapor. When the beaker is placed over the candle, it creates a closed system, limiting the supply of oxygen needed for combustion, causing the flame to extinguish.
Why did the water rise in the beaker When the candle burned out?
The water rose in the beaker because as the candle burned, it consumed oxygen in the air inside the beaker. This created a partial vacuum, causing the water to be pushed up into the beaker due to the air pressure outside.
What happens when you put a beaker over a candle and why?
Putting a beaker over a candle can create a seal that limits the oxygen supply to the flame, causing it to extinguish due to lack of oxygen. This is because fire needs oxygen to sustain combustion, and by covering the flame, you are essentially cutting off its supply.
What will happen to candle in a beaker if carbon dioxide is added?
It'll go out

When you light a candle in a closed beaker why does the flame go out?
Oxygen is needed for burning.When a candle is kept in a closed beaker a certain quantity of air(containing oxygen, other gases too) is trapped. When it is burnt then candle starts using all the oxygen to convert into carbon dioxide and flame goes off.

What happens when you light a candle over a cold beaker?
When you light a candle over a cold beaker, the heat from the flame warms up the air around it. The warm air rises and surrounds the beaker, eventually heating it up. This process is known as convection.
What is the chemical reaction when you burn a candle inside a glass beaker?
It is an oxydation reaction.
Why is the beaker coverd with watchglass when heating the combine solutions of barium chloride and sodium sulfate solution on a waterbath?
protect the heat effect from the sun
Why would the time to put a candle flame out vary on the size of beaker put over the candle?
The time to put out the candle flame with a beaker varies based on the size of the beaker because larger beakers have more trapped air volume, which can limit the flow of oxygen reaching the flame. As the flame consumes the available oxygen in the beaker, it will eventually be extinguished once the oxygen level becomes too low to sustain combustion. Larger beakers will take longer to deplete the oxygen supply, hence taking longer to put out the flame.
How long can a candle burn under beakers of different sizes?
This delightfully simple experiment may be used to estimate the percentage of oxygen in the air. Assumption is that all the Oxygen is consumed. Mount candle on a small watchglass floating on water, light the candle, and place an inverted beaker over the whole to create a water seal. Measure the rise of the water inside the beaker.
