Final answer:
The type of energy resulting from the burning of wood or gasoline is thermal energy, which is produced through the transformation of chemical potential energy.
Step-by-step explanation:
When wood or gasoline burns, chemical potential energy, which is stored in the chemical bonds, is transformed into thermal energy. Thermal energy is the energy that results from atomic and molecular motion, and is typically experienced as heat. In the process of combustion, such as when wood or gasoline burns in the presence of oxygen, the chemical bonds are broken and new bonds are formed in the products. During this exothermic reaction, energy is released in the form of heat and sometimes light, exemplifying a conversion from chemical energy to thermal energy.
