What happens when u burn a candle?

Last Updated: 1st March, 2020

As the candle burns, solid wax becomes liquid and then evaporates to become a gas. The gaseous wax burns in oxygen to produce water, carbon dioxide, heat and light. The burning candle also produces carbon, in the form of the black soot we see on the spoon.

In this manner, what happens to candle wax when it burns away?

The heat of the flame vaporizes the wax molecules and they react with the oxygen in the air. As wax is consumed, capillary action draws more liquid wax along the wick. As long as the wax doesn't melt away from the flame, the flame will consume it completely and leave no ash or wax residue.

what are the products of a burning candle? When a candle burns, the reactants are fuel (the candlewick and wax) and oxygen (in the air). The products are carbon dioxide gas and water vapor.

Moreover, is it safe to burn a candle in a closed room?

A candle burns carbon molecules. If you sleep with a burning candle in closed room. Room will have limited amount of oxygen. Candle will continuously consume oxygen and convert it into carbon dioxide and carbon monoxide.

What is necessary for a candle to burn?

For a candle to burn, a heat source (commonly a naked flame from a match or lighter) is used to light the candle's wick, which melts and vaporizes a small amount of fuel (the wax). Once vaporized, the fuel combines with oxygen in the atmosphere to ignite and form a constant flame.

Where does candle wax go when you burn it?

When you light a candle, the heat of the flame melts the wax near the wick. This liquid wax is then drawn up the wick by capillary action. The heat of the flame vaporizes the liquid wax (turns it into a hot gas), and starts to break down the hydrocarbons into molecules of hydrogen and carbon.

How much oxygen does fire consume?

Oxygen. Air contains about 21 percent oxygen, and most fires require at least 16 percent oxygen content to burn. 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 is the purpose of a candle wick?

A candle wick is usually a braided cotton that holds the flame of an oil lamp or candle. A candle wick works by capillary action, conveying ("wicking") the fuel to the flame. When the liquid fuel, typically melted candle wax, reaches the flame it then vaporizes and combusts.

What are the products?

Products are the species formed from chemical reactions. During a chemical reaction reactants are transformed into products after passing through a high energy transition state. This process results in the consumption of the reactants. The materials are reactive and reactants are rearranging during a chemical reaction.
