Imagine being able to use your computer to make phone calls with the help of special software and a microphoneâand bypassing your phone company and their charges.
So O2 has zero of heat of formation (or enthalpy of formation). The enthalpy of a reaction is defined like this: H = Hproducts-H reactants. The enthalpy of reaction in this case, is the same as the heat of combustion. Hproducts is obtained summing the heats of formation.
One part of the heat is produced in the combustion chamber of the tiled stove or the fireplace, and is thus emitted directly from the epicenter. The heating gases, which emerge in the combustion chamber and have a temperature of approx.800Â°C, contain the other great part of the energy. By using different heat exchanging devices, the temperature is detracted from these energy amounts and can thus be used as heat.he heating gases, which emerge in the combustion chamber and have a temperature of approx. 800Â°C, contain the other great part of the energy.
