Polynomial Curve Fitting Often we can assume that certain thermodynamic properties are constant for the process under study. However if there is a large change in temperature during a thermodynamics process this assumption can lead to significant errors; a typical example would be combustion in an engine. In such cases tables can be used. However, tables are awkward to use for computer calculations; therefore, a polynomial equation is often used in computer programs that simulate thermodynamics processes. As an example...
