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!

The wick of a candle burns, and with it the wax of the candle.

when wax of the candle burns it is a physical change but when wick of the candle burns it is a chemical chang

the wick Burns but it produces heat that melts the wax

The wax on the candle can turn in a gas

It vapourises and burns.

As the candle is burning, some of the wax melts and turns into a gas in the atmosphere.

As a candle burns, the candle becomes smaller as the wax melts.

Chemical =the candle burns Phisycal=the wax melt

Well no not that candle itself. really on the wick there is wax and that is the thing that actually burns but the hot wax coming down makes it look like the candle burns.

Candle wax is a hydrogenated oil compound

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.

the wax burns up and continuosly drips down the wax burns up and continuosly drips down

The wax is the main thing burning to sustain the flame but eventually the wick burns as well. Essentially it is the whole candle that burns.

it depends on the type of wax used, not the color

The chemical energy stored in the candle wax.

One example is melting of the candle wax to produce the liquid that actually burns when a candle is lighted.

When you try to light a piece of solid wax, it melts, but it does not burn. If solid wax doesnt burn, how does a candle burn? Is it the string wick that is in the middle of the candle that burns? String will burn, but it doesnt burn like a candle does. How then does a candle burn? When you light the wick of a candle, the wax at the top of the candle melts. The molten wax is drawn up the wick just like water soaks to a paper towel. As the wax flows up, the wick gets closer to the heat of the flame, then evaporates. The wax vapour mixes with the oxygen in the air and burns

No. Not all candles are made of wax. A candle can be made of soap, oil, fat.

When you light a candle, it burns the wax. That is chemical energy. The thermal energy is produced as the lighted wick continue to burn the wax. It also gives out light as it burns.

Candle oil is oil that has been turned in to wax in a burning hot room called a frets.

because, when the wax is lit it burns off as a vapor, when the candle was extinguished the wax vapor was still in the air, and the wax acts as fuel for the flame of a candle, so the flame combusted and lit the vapor, leading back to the candle wick.

the first wax was a candle

The length of time that a candle burns isn't dependent on the manufacturer of the candle, but on the diameter of the candle and the density of the wax. For example, a taper candle (tall and skinny) will burn more quickly than a pillar candle (more an an inch or two in diameter). A solid wax candle, being more dense, will burn more slowly than a honeycomb candle which is a little bit of wax with lots of air cells in it.

The thickness of the wick mostly determines the burn rate. The rate, as used above, is the speed with which the candle wax is consumed, not the rate that the candle burns downward.

The solid wax of the candle melts, and eventually vapourises, then burns and becomes a gas.
