Generally more energy is in a solid versus a liquid, so a wax candle will have more energy than an oil based candle which means the solid wax candle will burn out last over the oil one. Actually, I can't think of a case where the reverse is true. And btw, wax candle has around 42 kJ/g with oil candle being around ~30 kJ/g (type of oil will make a difference here).
tho' i agree with most of the above, the most important part of any candle is the oil/oil byproduct/animal fat or beeswax that it is made from! a wax candle will NOT burn until it heats up enough to dissolve into an oil - which occurs between 140-160 degrees! therefore, an oil candle and a wax candle burn out at the same time!
What else can I help you with?
What happens to the wax as the mass of the candle gets less?
Just like logs on a campfire or oil in an old-fashioned lamp, wax in a candle is actually fuel for the flame itself. The candle continues burning as long as there is wax to be melted & soaked into the wick. As it burns, the wax oxidizes into water vapor, CO2, and, of course, light. Wax continues to melt around the flame and soak up the wick to be used as fuel, causing the candle appear to "disappear" as we watch it burn.
Why cant a candle last forever?
Because a candle is made of wax and the fire which is on the wax melts it making it smaller and smaller until it disappears. The same occurs to the wick (the bit that actually burns) The candle contains a flamable liquid, normally an oil which soaks in to teh wick and then is burned off
Which is to burn longer a tallow candle or a wax candle?
If you freeze the candle, before using it, it will burn for a longer period of time. ANSWER Beeswax burns very quickly.
Which color candle burns the slowest?
The rate at which a candle burns is dependent on the size and composition of the wick, and the thickness, composition, and melting / vaporization rate of the candle wax. Color is not the dominant factor in candle burning rates.
When a candle burns what is the most prevalent products are what?
When a candle burns, the most prevalent products are water vapor, carbon dioxide, and heat. Additionally, depending on the type of wax used in the candle, there may also be trace amounts of soot and other byproducts.
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.
What does the wax of a candle react with when it burns?
Oxygen.
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 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.
Is candle wax mixture or a compound?
Candle wax is a hydrogenated oil compound
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.
