What is when a candle burns and liquid wax is forming?
When a candle burns, the heat melts the wax, which then becomes liquid and flows down the sides of the candle. This process is called wax pooling. The liquid wax provides fuel for the flame to continue burning.
How does the state of matter of wax in a candle change when the candle it lit?
When a candle is lit, the solid wax melts and turns into liquid wax. As the candle burns, the liquid wax is drawn up the wick by capillary action and evaporates, creating a gas that then burns and produces heat and light.
What burns on a candle the wick or the wax?
the wick Burns but it produces heat that melts the wax
How does a candle change physically?
As a candle burns, the candle becomes smaller as the wax melts.
What gas in the air burns when candle wax melts?
The candle wax melting exposes the wick, where the actual burning takes place. Oxygen in the air combines with the vaporized wax in the wick, generating heat and giving off carbon dioxide (also traces gases and often carbon soot). (see related link)
What physical and chemical changes occur when a wax candle burn?
Some wax burns, and as it does so, chemical changes occurs. Wax converts to CO2, CO, and H2O. That is an exothermic reaction The rest of the wax melts with the increased temperature. That is the physical change.
Burning candle what is actually burning?
Vapours of the candle wax, which contain carbon and hydrogen, react with oxygen in the air to create carbon dioxide and water. Often, the combustion is incomplete and small amounts of carbon monoxide as well as carbon (soot) are released.
Where does the wax of a candle goes when it burns?
When a candle burns, the wax is drawn up the wick and vaporized into carbon dioxide and water vapor, releasing heat and light. The wax is essentially converted into these gases and released into the air.
What physical changes happen when a candle is lit?
There are many things that physically chance when a candle burns. The wick burns, and turns into ash, and wax of the candle melts and runs down the sides of the candle or container.
Where is the wax of the candle going?
The wax of the candle is being consumed through the process of combustion. As the wick burns, it melts the wax, turning it into vapor and releasing carbon dioxide and water vapor into the air.
What is the change of state in a lit candle?
The change of state in a lit candle is from solid (wax) to liquid (molten wax) to gas (vaporized wax) as the heat from the flame melts the wax and turns it into vapor that burns, releasing heat and light.
What changes do you see when a candle burns?
When a candle burns, the wax at the top of the candle melts and turns into liquid, which is then drawn up the wick by capillary action. This liquid wax vaporizes and mixes with oxygen in the air, producing a flame. The heat from the flame melts more wax, sustaining the process and allowing the candle to continue burning.
