Theoretical heat of combustion of ethanol
WebbHeat of combustion lab report. Chemistry Lab Report Aim: The combustion of organic compounds produces large quantities of energy. These compounds range from that of alkanes, to alkenes to even alcohols. Ethanol is a commonly used fuel in motor-cars and its usage is increasing because it is a form of renewable energy. Webb1 sep. 2012 · As the ball cools, heat is transferred to the fuel bed, and if this occurs at a sufficiently great rate, a steadily propagating travelling wave will be established that will eventually consume the entire bed. However, there are well-defined sets of initial conditions for which the travelling wave stalls, resulting in partial consumption of the ...
