When you burn a log in the fireplace why is there a difference in mass?

The chemical composition of a log (and most organic substances) is carbon. Carbon when burned becomes oxides of carbon which are usually gases i.e. carbon dioxide and carbon monoxide. Therefore in essence, most of your log is being vaporized. If you were to burn the log in an enclosure such that none of the gases were lost, you would observe no mass difference.

∙ 13y agoIf you burn a log in an closed container (with enough oxygen) the entire container with ash will weight as much as the entire container with the log.
If you burn a log in the open it will be heavier than the ashes it forms.
This mean that gases are escaping. Because a log is made of wood and wood is made of cellulose, a carbohydrate, we can assume the change in mass comes from the CO2 formed and the water that evaporates.

How do you calculate a log with 9 diameter and 10' length?
You do not calculate a log!You can calculate the surface area or the volume or, if you know the species, the mass or even time for which it would burn in a hearth. But the log, itself, is not something you can calculate.You do not calculate a log!You can calculate the surface area or the volume or, if you know the species, the mass or even time for which it would burn in a hearth.
