Why does fire grow with oxygen but go out when you blow on it?

They are simply too hot to be stopped by blowing at it, and actual blowing temporarily increases the airflow in the fuel supply, allowing more oxygen to react with the fuel. This causes the flame to grow hotter.

What happens to oxygen when a candle burns?

When we ignite the candle, the 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.

Why does a burning candle go out when you blow on it your answer?

Answer: When we blow air on a burning candle, we remove the hot air around the flame. In this way, we reduce its temperature below the flash point. Thus, the candle goes out.

Why does oxygen feed fire?

Oxygen. Oxygen supports the chemical processes that occur during fire. When fuel burns, it reacts with oxygen from the surrounding air, releasing heat and generating combustion products (gases, smoke, embers, etc.).

What happens if you blow out a candle?

First, blowing out a candle can ruin the hours you spent burning it for its scent, as it replaces the fragrance with the smell of smoke. The technique can also be risky, as it has the potential to send sparks into the air.

How does an oxygen candle work?

Oxygen is produced from a thermal, chemical reaction. Oxygen candles house a mixture of sodium chlorate, barium peroxide and iron powder; the oxygen-producing chemical is sodium chlorate. This reaction produces oxygen, sodium chloride (common salt) and iron oxide through a process known as thermal decomposition.

How much CO2 does a candle produce?

Burning a paraffin candle for one hour will release about 10 grams of carbon dioxide. that is10X more than burning a cracker. Each day around 3 BILLION candles burnt in Church and Home crossed. Each candle produces 12 GMS CO2 and is 10 times higher than a single cracker.

What are the three main ways in which a fire can be controlled or put out?

What are the three main ways in which a fire can be controlled or put out? Solution: Fire can be put out by taking away the fuel, stopping the supply of oxygen or by lowering down the temperature around the fuel, so that the fuel is not able to attain its flash point.

What are the three main ways in which a fire can be controlled?

Answer: The fire can be controlled or put out in the following three main ways : (i) We should take away the fuel. (ii) Ordinary fires can be put out with a damp blanket or a sack, (iii) We should remove the heat.

Can fire exist without oxygen?

A fire cannot burn without oxygen. It should be noted that in the presence of carbon, nitrogen and oxygen, stars heavier than the Sun may burn hydrogen to helium by using the C, N and O as catalysts. Even in these stars, however, an absence of oxygen does not prevent nuclear burning.
