I am working on a chemistry lab write- up. The goal of the experiment is to determine what the burning rate of a candle is.
For the experiment, each group recieves two candle, one a birthday candle, another a home candle (about 1.5 cm diameter and 20 cm height.) We had to record either how many cm of ea ch candle were lost or how much volume was lost, after 10 minutes of burning.
But before that, we had to determine what the burning rate is for candles.
And this is where my question lies: Would the burning rate of a candle be expressed as time/ volume or time/ cm?
If you have any ideas, please tell me and it would be excellent if an explanation comesa along with it.

The burning rate of a candle would be volume/time. As a candle-maker, I determine the burn rate or total burn time by using the weight of the candle before and after the specified burn time. The burning rate can't be determined until after the candle has been burned for the specified time. A 25 ounce candle that burns at the rate of 1/4 ounce per hour has a total burn time of 100 hours.

Any Rate is expressed by "something per unit of time"--e.g. miles per hour. Your burning rate for a candle could be either volume/time (cubic centimeters/second (or minute or whatever unit) or height. If you are trying to make a standard across many candles, using volume would be most consistent.

cm
It is easier and as reliable if you use the same quality and diameter candles.
To about 4 cm diameter all will burn up. From about 4 or 5 cm there will be a hole in the candle and you can think about using cm3.
Don't make it harder than it has to be.
