Investigating Factors Affecting the Heat of Combustion of Alcohols

Brief Introduction of Research Factors Affecting Alcohol Combustion Heat ------------ Alcohol is an organic substance composed of hydrogen, oxygen and carbon. Every alcohol is toxic, but the amount that the body can tolerate depends on the alcohol. For example, drinking a small amount of methanol may cause blindness or even death. Ethanol is the only alcohol that can be safely ingested and can be contained in all alcoholic beverages. Through investigations, we will consider various factors that affect alcohol decomposition.

Alcohol: Investigation plan of combustion heat of five kinds of alcohol ======== Introduction ------------ I tried to find the heat of combustion of the first five kinds of alcohol, yes , Ethanol, propanol, butanol, pentanol and hexanol. I tried to determine if the number of carbon atoms in the molecule had an effect on the heat generated from the molecule during combustion. - On a beautiful summer day, lively tourists invaded the coast of Nassau. When the sea touches the coast, it becomes filled with the love of the waves and a perfect romantic entrance can be made. One of the tables at the Beachfront Restaurant in Nassau changes the lives when people enjoy the beautiful weather along the coast. A simple gesture of lighting a cigarette shows the beginning of a new life in Charlotte Valley.

Investigate the change in the enthalpy of combustion of alcohol homologs. When carbon alcohol is burned, we study how alcohol with increased amount of carbon affects metamorphism. The energy released by alcohol when it is used is called the enthalpy of combustion. By using what I already have, I think alcohol with a large number of carbon atoms in the molecule will have greater alcohol change than alcohol with fewer carbon atoms. Therefore, as the molecular weight increases, I predict that the enthalpy of combustion increases.

Testing We use a calorimetric method to investigate the relationship between structure and heat caused by a series of alcohol burning. To do this, burn alcohol and let it heat a large amount of water. To measure the temperature rise of this mass of water, you can use this formula to find the thermal energy released during the reaction.
