Entropy changes in isothermal transformations

For any isothermal change in state, T, being constant, can be removed from the integral in Eq. (9.2), which then reduces immediately to [Pg.172]

The entropy change for the transformation can be calculated by evaluating the quantities of heat required to conduct the change in state reversibly. [Pg.172]

By the same argument, the entropy of fusion at the melting point is given by [Pg.173]

For many liquids, the entropy of vaporization at the normal boiling point has approximately the same value  [Pg.173]

Equation (9.8) is Trouton s rule. It follows immediately that for liquids which obey this rule, [Pg.174]
