Best Answer

When wood burns, essentially organic molecules within the wood is oxidized into carbon dioxide, among other oxidized carbon forms. The various oxidized carbon forms are mainly gases and is released into the atmosphere. Because after the wood is burned out, the majority of the organic material has been converted into the gases, much of the wood's mass is lost.

Carbon from the wood combined with oxygen from the air and turned the wood into carbon dioxide. The water is vaporized and are now in the atmosphere.

Yes, as the wood burns, part of the mass is converted into mass and the rest is converted into CO2 which is a gas therefore, not visible.

Maybe because Carbon particles of the log react with the oxygen in air to form CO2 which rises to the atmosphere.

Will putting wet wood on a bed of coals in a wood stove create creosote in chimney?

Creosote is not created- it is naturally in the wood. A "cool" burn lets the creoste present in the smoke condense on the walls of the chimney. With a hot burn, the flue gasses are hot enough that less is deposited on the chimney. Wet wood gives a cooler burn.

They sell baskets for burning wood pellets in fireplaces. Are they any good?

Wood pellets are intended to burn under a forced draft. They will not burn as well in a fireplace- why not use regular firewood? It is much less expensive than the wood pellets, and will burn as well in a fireplace. PS- a fireplace is a very poor choice for heating a home.
