Arguments advanced for this lack of concern are that the average person with cardiac problems is too old to be concerned with sexual activity, or that persons with disabilities can not engage in secual intercourse or are not inclined to do so (Sidman, 1977).
When forest fuels burn, there is a chemical combination of the oxygen in the air with woody material, pitch and other burnable elements found in the forest environment. This process in known as Combustion. Combustion is a chain reaction chemically similar to photosynthesis in reverse. Photosynthesis requires a large amount of heat which is furnished by the sun. The Combustion process releases this heat.
Combustion, better known as burning, is the combination of a substance with oxygen. The products are carbon dioxide, water, and possible other waste products. Combustion reactions release large amounts of heat. C 3 H 8, better known as propane, undergoes combustion. The balanced equation is: Combustion is similar to a decomposition reaction, except that oxygen and heat are required for it to occur. If there is not enough oxygen, the reaction may not occur. Sometimes, with limited oxygen, the reaction will occur, but it produces carbon monoxide (CO) or even soot.
