This Research aims to study some thermodynamics properties for some organic liquids depending on the law of corresponding states using the dimensionless variables ( transferred Parameters ) in the law of condition for liquids and gases . These variables are considered to be very important in practical application because its values at the critical point are equal to one in all materials . In our research we will use the algorithm method to calculate these properties for some organic liquids depending on the values of these parameters which have been calculated by experimental methods by some researchers . And then we will use them as primary data to conclusion these properties according to the algorithm method and then compare the result we get with the result in other researches .
