In this report, the properties of oxygen based on the Redlich-Kwong(RK) is considered. The aim of this paper is to find the enthalpy, entropy, and the internal energy of the CO2. In first step, the Redlich-Kwong equation of state is introduced then the related parameters are calculated with respect to the considered material. Afterward, the properties (h,u,s) are determined both by numerical methods and EES. Ultimately, the results are compared in both approaches in different temperature and pressure
