Which type of energy is fire categorized as?

Fire is categorized as thermal energy because it involves the transfer of heat due to combustion reactions. When materials burn, they undergo a chemical change that releases energy in the form of heat and light. This heat results from the movement of particles at the molecular level, which is characteristic of thermal energy.

While kinetic energy relates to the motion of objects and potential energy pertains to the stored energy in an object's position or configuration, these do not accurately describe the nature of fire. Similarly, electrical energy involves the flow of electric charge, which is unrelated to the phenomena of fire. Thus, classifying fire as thermal energy aligns with its fundamental properties as a source of heat.
