Explanation / Answer

Combustion of wood is essentially any fuel

Fuel + O2 --> CO2+ and H2O

plenty of material will go as CO2 gas and H2O vapor... The non-fuel or non-volatile material will remain as "ashes"

If you were in a "bubble" you could mantain the gases from evaporating and you will remain the total mass
