A burning fire is exothermic because a lot of heat is given off as the wood is converted into carbon dioxide and water.

A burning fire is endothermic because a lot of heat needs to be applied in the form of fire to break the bonds of the wood.

Answer 1

A burning fire is exothermic because a lot of heat is given off as the wood is converted into carbon dioxide and water. Although some energy (activation energy) is needed to start the reaction, the overall reaction releases more energy than it consumes.
