Maybe a better question is whether a candle AND it's combustion products gets heavier or lighter. Since a candle uses the oxygen from the air, the total mass gets heavier than the original candle.

∙ 11y agoBurning candles lose mass through four ways:
- Candle wax melts, and the molten wax rises up the wick through capillary action whereupon the molten wax evaporates due to the heat at the base of the flame. The wax vapors burn in the flame. This chemical oxidation process converts the candle wax into combustion byproducts that rise up as smoke from the flame.
- Some candle wax vapors escape before burning, and dissipate into the air.
- Candles can drip molten wax, which fall off the candle before evaporating.
- The wick itself burns, and is converted into combustion byproducts that either rise up as smoke or fall off as ash.

∙ 14y agoBecause of the law of conservation of mass, the mass of the candle does not disappear when it is burned. This means that the whole mass is converted to other substances, the products of the combustion reaction. The mass of these products must be equal to the mass of the reactants, in this case, the oxygen, wick, and candle that are burned.

Which color of candle burn faster in candle race that is theory?
Cream is the colour
How is the acceleration of a mass changes if the force applied to it increases or decreases?
Acceleration increases when force increases and decreases when force decreases.
Why does a unscented candle burn faster then a scented candle?
unscented candles burn faster because its made with a type of wax that doesnt have fuuels and the less the fuels the faster it burns
Why does a long candle burn faster than a short candle?
They are usually thinner and the Warmness don´t get that isolated
If mass decreases does density increase?
No its density decreases assuming volume remains constant. Density is defined as mass / volume, so if mass (the numerator) decreases but volume (the denominator) doesn't change, the quotient will decrease.
What candle would burn faster a white candle or a purple one?
wouldn't make a difference if they were the same shape,mass,and volume
A paraffin wax candle is used to heat up a can of water. The candle had a mass of 15.75g before the burn and 14.20g after the burn The can contained 250.0 of water at an initial temperature of 13.0 C?
A paffin wax candle is used to heat up a can of water. The candle had a mass of 15.75g before the burn and 14.20g after the burn. The can contained 250.0 of water at an initial temperature of 13.0 C. What is the heat of combustion in kJ/g of paraffin? The specific heat capacity of water is 4.184 J/(g C)
When a candle is allowad to burn in open air the mass of the candle decreashow can you explain this?
Wax evaporates as well as melting. Mass is therefore lost, as the wax turns into various gaseous molecules which escape from the solid body.
How does burning candle affect mass differently than melting a candle?
When a candle burns, it undergoes a chemical reaction called combustion, where the wax reacts with oxygen to produce carbon dioxide and water vapor. During this process, the candle's mass decreases as some of the wax is converted into gases. On the other hand, when a candle melts, it transitions from solid to liquid state, but its mass remains unchanged as no chemical reaction occurs.
If a plant and a burning candle are placed under a bell jar will the candle burn?
no it will not it needs carbon dioxide to burn, without it theres no way the candle will be able to burn
Which one takes longer to burn rubber or a candle?
a candle takes longer to burn but it smells nicer, especially if it is a scented candle
When was Burn Like a Candle created?
Burn Like a Candle was created on 1972-06-25.
Does a candle burn the brightest towards the end?
yes, candle will burn brighter before extinguision
What is the reason for a yellow candle to burn faster than a colored candle'?
actually the color does not effect how fast the candle burn, i got confused of " Does candle's color effect how candle's burn?"but i think the color does not effect how candle burns. But some people will think that the white or yello candle will burn slower because color will obsorb the heat more. Hope i have answered your question.
Why does floating candles float higher in the water as they burn?
the mass decreases as the wax burns so it displaces less water
Does the thickness of a candle affect the burn time of a candle?
Yes, thicker candles have more wax to burn and therefor take longer to burn out.
How does mass affect density if the volumes are the same?
If the mass increases, the density decreases. If the mass decreases, the density decreases.
