Why do damp clothes become dry when hung outside

Why do damp clothes become dry when hung outside  [Pg.134]

Everyone knows damp clothes become dry when hung outside on the washing line. Any residual water is lost by evaporation from the cloth. In fact, moisture evaporates even if the damp clothes hang limp in the absence of a breeze. The water spontaneously leaves the fabric to effect the physicochemical process H20(i) — H20(g). [Pg.134]

Worked Example 4.2 By inspection alone, decide whether the sublimation of iodine (Equation (4.3)) will occur spontaneously or not  [Pg.134]

Molecules in the gas phase have more entropy than molecules in the liquid phase and molecules in the liquid phase have more entropy than molecules in the solid state. As an excellent generalization, the relative order of the entropies is given by [Pg.134]

The product of sublimation is a gas, and the precursor is a solid. Clearly, the product has greater entropy than the starting material, so A 5 increases during sublimation. The process is spontaneous because A 5 is positive. [Pg.134]
