how chemical energy produce in firewood useful
Burning wood is a chemical change because burning is a chemical reaction - oxidation (reaction with oxygen). This reaction is exothermic - release heat.
As the wood burns, the molecules inside of the wood are broken and causes heat to be released.
you use chemical energy by cooking an egg, burning wood, water on wood/metal
Burning wood is a chemical reaction because combustion (burning) is an oxidation reaction.
Chemical energy is the potential of a chemical substance to undergo a transformation through a chemical reaction or to transform other chemical substances. Examples of chemical energy are: the digestive process, batteries, photosynthesis, burning gasoline, burning wood, using TNT, fire works, putting salt on a slug, alcohol, fermentation, and rusting.
The burning of a wooden stick is a chemical process.

Energy cannot be created. (Or destroyed) Burning changes the chemical energy of the wood to heat energy and light energy.
Yes.
The stove itself is not but if it is a wood burning stove, when it is used, the conversion of wood into heat is the conversion of chemical into thermal energy
Wood has chemical energy that can be converted into light by burning the Wood. Nitroglycerin has chemical energy that can be converted into sound by shaking it (Don't try this at home!).
usually by burning the wood and making use of the heat.
No, it's the other way around. Burning releases the chemical energy in wood and turns it into thermal energy(heat.
During burning (oxidation) the heat of combustion is released.
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.
By burning it.
Wood has chemical potential energy, when combustion occurs, you have fire. Fire is mostly heat and light energy.
Burning of coal, wood and oil..Chemical-heat energy.HOPE I HELPED!:)
