Re: Does the shape of an amount of candle wax affect how long it burns?

The shape of an amount of candle wax could have some effect on the rate it 
burns but it wouldn't have any effect on the total amount of energy it 
gives off when it is burned.  The amount of energy given off by a quantity 
of candle wax is governed by the heat of combustion of the wax. If the 
candle burned slowly, the candle would last longer and the energy would be 
given off more slowly, and if it burned rapidly the candle would not last 
as long and the energy would be given off more rapidly - but the total 
amount of energy released would be the same no matter how the candle was 
shaped.
