To predict the performance of a given set of chemical propellants (fuel plus oxidizer) or a more advanced propulsion system, it is possible to calculate I sp based on the properties of the exhaust gases (temperature, pressure, composition, etc.). It is found that I sp is strongly dependent upon the temperature (T) and average molecular weight (M) of the gases.
