Air exhaled contains a higher concentration of carbon dioxide, which can act as a fire extinguisher.
OR
The fast moving air causes a reduction in the heat available to the candle flame, thus extinguishing it. Heat is one of the 3 essential components of the fire triangle, the other 2 being fuel and oxygen.
When you "blow out" a candle flame, you are rapidly reducing the temperature of the wick and cooling the burning material to below the ignition point.
What else can I help you with?
Why does a candle flame go out when you blow it?
To burn the candle flame needs a steady supply of oxygen from the air. Dry Ice is solid Carbon Dioxide and as you pour the dry ice gas over the flame you displace the air from around the flame and replace it with Carbon Dioxide. Starved of Oxygen the flame goes out.
What gas would make a candle go out?
Naturally, it is Carbon Dioxide because it is denser than oxygen which is a gas needed for combustion.
How does oxygen affect how long a candle burns for?
Oxygen is necessary for combustion to take place. When a candle burns, it reacts with oxygen in the air to produce a flame. Increasing the oxygen supply will result in a hotter and more efficient burn, causing the candle to burn more quickly. Conversely, reducing the oxygen supply will cause the flame to burn more slowly or even extinguish.
Why do you pucker your lips when blowing out a candle?
We pucker our lips while blowing candles to concentrate the flow of air at the target (candles),if the lips are not puckered then it would lead to the dispersal of air and desired result might not be achieved.
Why do we pucker our lips when blowing out a candle?
Puckering our lips helps to focus the airflow and direct it more precisely towards the candle, which makes it easier to blow out. It also creates a smaller opening, which increases the speed of the air leaving our mouth, aiding in extinguishing the flame.
Why does a candle extinguish when a fan is blown at it?
The fast moving air blown at the candle reduces the heat available, which removes an essential element of the fire triangle, causing the flame to extinguish.
What is the effect of dry ice vapor on a candle?
sublimation The vapor from the dry ice will extinguish the flame from the candle.
Why does the candle flames go out when you blow it?
When you blow out a candle, you disrupt the balance between the oxygen supply and the fuel (wax) being consumed by the flame. When you remove the oxygen by blowing, the flame no longer has the necessary element to sustain itself, causing it to extinguish.
Why does candle blow off when covered?
When a candle is covered, the surrounding air becomes depleted of oxygen due to the flame consuming it. Without oxygen, the flame cannot sustain itself and will eventually extinguish, causing the candle to go out.
Why does a candle flame go out when you blow it?
To burn the candle flame needs a steady supply of oxygen from the air. Dry Ice is solid Carbon Dioxide and as you pour the dry ice gas over the flame you displace the air from around the flame and replace it with Carbon Dioxide. Starved of Oxygen the flame goes out.
Why fire increases on blowing exhaled air to coal chulla or bhatti while candle extinguish on blowing exhaled air?
When blowing on a fire it increase air flow. This in turn provides more oxygen which fires need to sustain themselves. In the case of candles, they are too small to handle the air flow.
If you lift the glass tumbler which is placed over a burning candle to 1cm height what hapens?
Lifting the glass tumbler placed over a burning candle to a height of 1cm could disrupt the airflow around the candle, affecting its ability to receive oxygen. This may cause the candle flame to flicker, decrease in size, or even extinguish depending on how much air is allowed to reach the flame.
What gas would make a candle go out?
Naturally, it is Carbon Dioxide because it is denser than oxygen which is a gas needed for combustion.
How does oxygen affect how long a candle burns for?
Oxygen is necessary for combustion to take place. When a candle burns, it reacts with oxygen in the air to produce a flame. Increasing the oxygen supply will result in a hotter and more efficient burn, causing the candle to burn more quickly. Conversely, reducing the oxygen supply will cause the flame to burn more slowly or even extinguish.
How long can flame last without air?
Combustion or burning requires oxygen of the air. So, if there's no air, the flame will extinguish immediately because there's no oxygen.
Does candle flame move east to west?
No, the movement of a candle flame is predominantly influenced by air currents and the direction of the draft in the surrounding environment. The flame will flicker and move in various directions based on these factors rather than being consistently oriented from east to west.
Why do you pucker your lips when blowing out a candle?
We pucker our lips while blowing candles to concentrate the flow of air at the target (candles),if the lips are not puckered then it would lead to the dispersal of air and desired result might not be achieved.
