Matrix Representations of the Thermo-dynamic Functions used for Studying the Burning of Gas Combustibles

The paper contains data regarding the processes that occur art normal pressure and the variations of enthalpy, entropy, molar isobar heat, isobar potential. The variations of enthalpy and molar isobar heat are useful in the calculation of the thermic balance-sheet, and those in connection with the isobar potential are useful for the calculation of the balances. The enthalpy and entropy are linear combinations of the temperature functions and, being taken as a basis for the calculation of isobar potential. The indicated proprieties for each component can be calculated, if we know the approximation function for the isobar molar heat and the known value of the propriety at a temperature. In order to find the, coefficients we consider known the values of the molar isobar heat at five values of absolute temperature, after which we apply the linear algebra method.
