The heat from a candle is stored in the chemical bonds of the oxygen and the candle wax. When you use a match to light the candle, you are activating the chemical reaction between the oxygen and the wax, which releases the energy stored in the bonds of the wax and oxygen. The products of the reaction, carbon dixode and water, require less energy for their bonds. So, all the extra energy that was stored in the wax and the oxygen is released to the air around the candle (the extra air that's not being used to react with the wax). Remember, if you put a jar over a candle, it will go out because it runs out of oxygen to react with.
Water vapor from a candle comes from the combustion process when the wax in the candle melts and reacts with oxygen from the air, producing carbon dioxide and water vapor. The water vapor is a byproduct of this chemical reaction and is released into the air as a gas.
The energy comes from burning hydrocarbons which is what paraffin was is composed of. It is the same as burning natural gas or gasoline/petroleum. Carbon dioxide, water and heat are produced in this reaction.
obviously from the candle, or magicians I'm not really sure which is more right!
Some of it is, but mostly its carbon particles (soot) left from incomplete combustion.

Where did the carbon dioxide and water vapour come from 4.5 billion years ago?
earh
what is the molecular mass of water vapour?
The molecular mass of water vapour is 18.01528
Can water vapour be turned back to liquid?
Yes, in the atmosphere water vapour falls as rain.
Does water vapour does not have definite shape and have definite volume?
Water vapour does not have definite shape and does not have definite volume.
What is the difference between water vapour and steam?
the difference is that water vapour is just one particle that joins together with more and more to form steam
What is water vapour and where does it come from?
Water vapor is evaporated water, it is mainly caused by the heating of water by the sun.
A lit candle on a balance losses mass why?
The wax of the candle is made from hydrocarbons - compounds made up of carbon and hydrogen only.When hydrocarbons burn in a plentiful supply of air they all produce the gas carbon dioxide and water vapour, both of which dissipate into the air.So when a candle burns, its wax is slowly being converted into carbon dioxide and water vapour which disappear into the air surrounding the candle, and so its mass appears to decrease.However, if you collected all the carbon dioxide and water vapour given off by the burning candle, and weighed it, you would find that it weighed more than the wax from which it came, because in the process of burning he wax had combined with the oxygen in the air, thus increasing its mass.
Whats actually burning on a candle?
the flame of a candle is a reaction of oxygen with carbon to form carbon(iv)oxide and vapour

How does ice drops come from sky?
supersaturation of water vapour leads to the formation of ice crystal
How come vapor comes out when you twist to open a bottle of water?
Air has only a limited capacity to carry water vapour, this capacity diminishes as the air gets colder. When this happens, the water vapour will condense out, at first as a fine mist.
what is the molecular mass of water vapour?
The molecular mass of water vapour is 18.01528
What is water turned into gas called?
It is called water vapour or simply vapour.
What does water vapour do?
Water Vapour is a colourless, odourless gas which is made of tiny water droplets.
what does water vapour?
Water Vapour is a colourless, odourless gas which is made of tiny water droplets.
Why can you see clouds but not water vapour in the air?
It is because water vapour is air so it can't be seen but when we breath out in the mirror,water vapour is found.
Do water vapour has volume?
But of course the vapour of the water have the volume. but it is a less than the water itself goodbye.
