Why is the burning of a candle a physical change?
The wax melts, it can solidify into a solid again.
What happens to a candle when it melts?
When a candle melts, the heat from the flame causes the wax to melt into a liquid state. This liquid wax is then drawn up the wick via capillary action and vaporizes, creating a fuel for the flame to continue burning.
What is the purpose of a candle burner?
A candle burner, also known as a candle warmer is an electric warmer that melts a candle to release its scent. The advantages of using a candle warmers is the soot that often results from burning wax.
What does a candle need to burn?
Because candles need feul, oil, and oxygen to burn.Without oxygen it will burn out.
Name the different states of matter in which burning candle wax can resist?
Burning candle wax is in the liquid state as it melts, then transitions to a gaseous state as it vaporizes and combusts to produce a flame.
What is the difference between melting of candle wax and burning of candle?
Burning a candle is the process in which the wick is burnt. The wax is there to make the wick burn slower in order to let the candle burn for longer. Melting wax is part of the process but not burning the candle itself.
Where does the wax of the candle goes?
When a candle is burning, the wax melts and is drawn up the wick through capillary action. The heat of the flame vaporizes the liquid wax, which then reacts with oxygen in the air to produce water vapor and carbon dioxide. The wax is essentially being consumed by the flame and converted into energy and byproducts like soot.
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.
What substance is the primary fuel for a burning candle?
The primary fuel for a burning candle is the wax, typically made of paraffin or beeswax. When the candle wick is lit, it melts the wax, which is drawn up the wick through capillary action and then vaporized by the heat of the flame, creating light and heat.
What is the thing that relies on burning to produce light and heat?
A candle relies on burning to produce light and heat. The wick of the candle is lit, and the heat from the flame melts the wax, which is then drawn up the wick and burned to produce light and heat.
What are 4 physical properties of a candle?
The candle has a solid wax body that becomes liquid when heated. It typically has a wick at its center that is used for lighting the candle. It emits light and heat when burning. The candle eventually melts and decreases in size as it burns.
What happens to the matter of a burning candle after it burns?
The matter of a burning candle is transformed into heat, light, and various gases and particles, such as carbon dioxide, water vapor, and soot. The process is a chemical reaction in which the wax of the candle combines with oxygen from the air to produce heat and light.
