Question

Is a burning fire endothermic or exothermic? How do you know?(1 point)
A burning fire is exothermic because a lot of heat needs to be applied in the form of fire to break the bonds
of the wood.
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.
A burning fire is exothermic because a lot of heat is given off as the wood is converted into carbon dioxide
and water.

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.

This is true because an exothermic reaction is one that releases heat, and combustion is a classic example of such a reaction where chemical bonds in the fuel (wood) are broken and energy is released in the form of heat and light as new bonds are formed in the products (carbon dioxide and water).
