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.)

How does the candle and water experiment work?

Once the glass is standing on the plate, the burning candle uses up all the available oxygen in the glass, then goes out. As it does so, the air in the glass cools, and as it cools, the air pressure in the glass falls below atmospheric pressure. Water is drawn into the glass until the pressure is equalised.

Why do candle not burn in inverted glass?

The burning candle produces carbon dioxide and water in the form of water vapor. The glass becomes foggy due to this water. The flame goes out, of course, from a lack of enough oxygen in the glass. If the air in the glass cools down and its volume decreases, a negative pressure is created inside the glass.

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

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 happens if you put water on a burning 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.

Is the pressure inside the glass with candle increases or decreases?

The air is heated while the glass moves downwards. It expands and escapes before the glass touches the water. If the air in the glass cools down and its volume decreases, a negative pressure is created inside the glass. The water is pressed into the glass by the greater external air pressure.

What happens if you put a jar over a burning candle?

The substance that reacts with the candle wax is oxygen. It comes from the air. Putting the jar over the candle keeps oxygen from outside the jar from getting in. Running out of oxygen makes the flame go out.

What happens if you put a glass over a burning candle?

What happens if you cover a lit candle in a water basin with a glass? The burning candle produces carbon dioxide and water in the form of water vapor. The glass becomes foggy due to this water. The flame goes out, of course, from a lack of enough oxygen in the glass.

What happens to a burning candle if there is no oxygen?

Because twice as much oxygen is burned than carbon dioxide released, the air volume decreases. The physical aspect: the candle heats the air and expands it. When the oxygen is depleted, the candle goes out and the air cools. The volume of the air decreases and the water rises.

Can you extinguish candle with water?

Never use water to extinguish a candle. Water can cause the hot wax to splatter and might break a glass container. Make sure the candle is completely out and the wick ember is no longer glowing before leaving the room. Don’t touch or move the candle until it has completely cooled.

What causes a candle to explode?

Wax melts at very high temperatures and this is going to cause the area around the candle to get hotter and hotter. The hottest area of a candle is typically going to be the very center of the candle. Once things get hot enough, the glass container or vase is going to explode due to the heat.

What will happen if a burning candle is covered with a glass jar?

Why does water rise up from the bottom of a candle?

hydrocarbon reacts with oxygen (in excess) to produce carbon dioxide and water. The burning sets an air current which gives dome shape to candle flame and it helps to get complete combustion at the bottom and the outer surface of the flame. The hot air and products of combustion rise up above

Why does the water rise in the glass?

Hypothesis 1: The burning of oxygen is responsible for the reduced air pressure. Prediction – if the burning of oxygen is the sole cause of the change in pressure, we should expect to see the water in the glass rise at a more or less constant rate from the moment the environment is sealed until the burning stops.

Why does water rise when a flame goes out?

When the flame goes out, the air in the vase cools down and the cooler air contracts. The cooling air inside of the vase creates a vacuum. This imperfect vacuum is created due to the low pressure inside the vase and the high pressure outside of the vase.

What happens when you put a candle in a pitcher?

Experiment:Cover a burning candle with a pitcher so that the candle is in an air-tight room sealed by the water at the ground. Observations:After some time, the candle dims and goes out. Just before the candle dies, the water level rises to almost 1/10 th of pitcher height.
