WebThere are two kinds of enthalpy of combustion, called high (er) and low (er) heat (ing) value, depending on how much the products are allowed to cool and whether compounds like H. 2O are allowed to condense. The high heat values are conventionally measured with a bomb calorimeter. Low heat values are calculated from high heat value test data.

Zwolinski and Wilhoit defined, in 1972, "gross" and "net" values for heats of combustion. In the gross definition the products are the most stable compounds, e.g. H 2O(l), Br 2(l), I 2(s) and H 2SO 4(l). In the net definition the products are the gases produced when the compound is burned in an open flame, e.g. H 2O(g), Br 2(g), I 2(g) and SO 2(g). In both definitions the products for C, F, Cl and N are CO 2(g), HF(g), Cl 2(g) and N 2(g), respectively. dhoni helicopter shotWeb28 de fev. de 2024 · The coal is coked, a process of heating the rock in the absense of oxygen.
