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.
A combustion reaction is a major class of chemical reactions. Combustion usually occurs when a hydrocarbon reacts with oxygen to produce carbon dioxide and water.In the more general sense, combustion involves a reaction between any combustible material and an oxidizer to form an oxidized product.Combustion is an exothermic reaction, so it releases heat, but sometimes the reaction proceeds so slowly that a temperature change is not noticeable.Good signs that you are dealing with a combustion reaction include the presence of oxygen as a reactant and carbon dioxide, water and heat as products. combustion reaction is a major class of chemical reactions. Combustion usually occurs when a hydrocarbon reacts with oxygen to produce carbon dioxide and water.
