| Abstract: | The gathering theory of molecule is successfully used in the prediction of thermophysics properties. An equation for predicting evaporation heat of liquids obtained by means of gathering theory was modified. The available range of the modified equation is extended for T br < T r<0.9 to 0.43 < T r<9.7. The average differences are reduced form 4.13% to 1.94% at 0.43< T r<9.7, and form 2.11% to 1.57% at T br < T r<0.9, which makes the modified equation be used in the engineering. |
