Wood has_chemical energy_____ energy while a burning fire has__heat energy __ energy
Wood is a material that makes up the central part of the trunk and branches of trees. Wood is made up of complex hydrocarbons and a rich cellulose network of organic molecules. A wood stores chemicals energy.
Combustion process such as burning liberates heat energy in them. Burning occurs in the presence of oxygen. As the oxygen combines with the materials, heat becomes liberated to the surroundings. Burning is an exothermic process in which heat energy is liberated.
