Burning wood is a chemical reaction called oxidization. By the application of heat the elements in the wood are rapidly oxidized, combined with oxygen from the air.
The resultant energy is heat energy, heat energy has three forms:
radiant heat - where the heat travels in a straight line from one surface (the
flame or the wood) to another surface, in a straight line of sight.
Convection heat - where the heat is carried by a fluid, the air, from one surface to
another. (The flame becomes visible when the air is heated to
incandescence[visible light]), the surface can be air molecules or solid
materials.
conduction - molecular transfer of heat from surface to surface by contact. Such as the heat transfer through the wood(the wood heats up).
Heat energy always has these three forms.
*note: a flame is only superheated air or gasses that have become incandescent. Incandescence is a conversion of heat to light.
Light is a radiant energy that can be transformed to heat energy when it is absorbed by a material.
Energy cannot be created. (Or destroyed) Burning changes the chemical energy of the wood to heat energy and light energy.
Thermal energy........
Since the "law of conservation of energy" states that energy cannot be created or destroyed, all energy is never really destroyed only changed. Chemical energy is converted into thermal energy by certain chemical reactions, like combustion (when something is burned) or when fat is metabolized into heat for the body for example.
It just produces thermal energy, in the same way as burning coal or wood.
Wood has chemical potential energy, when combustion occurs, you have fire. Fire is mostly heat and light energy.
Radiant and thermal
'HEAT' energy
Energy cannot be created. (Or destroyed) Burning changes the chemical energy of the wood to heat energy and light energy.
Thermal energy........
Oil, gas and coal burning always releases light or radiant energy. This is due to the high temperature of the burning material in the flame, it becomes incandescent.
By burning it. The heat it lets off will be energy.
People have been burning wood for centuries to provide themselves with heat energy.
