Answer the following question given this paragraph: 

A camp fire is an example of basic thermochemistry. The reaction is initiated by the application of heat from a match. The reaction converting wood to carbon dioxide and water (among other things) continues, releasing heat energy in the process. This heat energy can then be used to cook food, roast marshmallows, or just keep warm when it’s cold outside.


Q: What kind of energy is released when the thermochemical reaction of a campfire converts wood to carbon dioxide and water?


A:
heat
