Endo and Exo reactions

      A exothermic reaction is when the reaction puts out heat and or light. Creating a flame is a exothermic reaction. Does it exert heat? Yes, when you make a campfire its usually to warm you up or make food, in this case making food is a endothermic reaction. Creating flames are also used as a source for light. When you light a candle you have a source of light, the combustion of the wick creates a flame and that flame puts out heat and light. Creating a flame is a easy thing to do, today we have matches, lighters and we can always use the natural way of creating a flame by rubbing two things together to produce heat. This reaction has enabled us to do many things in todays world. Combustion has allowed us to cook food which has prevented us to burn off bacteria so we don't get sick while eating our meats. In a oven the oven puts out heat and if we were making bread the dough would absorb the heat and would begin to rise and than we have bread. Combustion also has enabled us to learn more about solutes and solvents in the lab because we had to light gas for our bunsen burners. Since combustion occurs we can use the heat from it to do all of these things.
