Propane at 1 bar and 35 °c is compressed to a final state of 135 bar and 195 °c. estimate the molar volume of the propane in the final state and the enthalpy and entropy changes for the process. in its initial state, propane may be assumed as an ideal gas. use residual property equations and lee/kesler correlations.
