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.
the mass stays the same.
Both. Heated wood gives off gasses that burn. Charcoal (carbon) will also burn.
for wood to burn you need fire
Petrified wood- wood that has turned to stone. Any other wood WILL burn, some better than others.
to get different types of wood and burn them and watch and see which one burn the fastest
One way for a fire to burn at a different temperature is it's wood soft wood such as pine burn fast and hot but hard wood such as muscle wood burns slower and cooler but still hot enough to burn you so don't touch it
Less dense wood will burn fastest, such as balsa wood. In general, the faster a tree grows, the less dense the wood from that tree will be.
Depending on what you mean by "better", it doesn't burn better. It might burn longer but it is much harder to ignite, and does not burn as hot as less-dense wood.
Paper burns faster as there is less mass to burn and less energy in paper, If it were wood, due to the mass of the wood it would burn Longer and brighter and less lengthened and less brighter for Cardboard.
Avocado wood (and any natural wood) will burn. Heat value is similar to elm. More heat value than pine, less than oak.
more space for air (oxygen)
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.
No it is not safe to burn it.

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.
Eat less, burn more calories, be very patient. It took time to get big, it will take time to get smaller.
