← ScienceWhich outcome occurs when a desiccant is saturated with moisture?
A)Exothermic chemical lattice energy is released
B)Endothermic phase transition decreases binding✓
C)Molecular kinetic energy increases sharply
D)Azeotropic distillation point lowers fractionally
💡 Explanation
The desiccant undergoes an endothermic phase transition, drawing heat from surroundings because water molecules weaken the desiccant's internal bonds during adsorption. This cooling, rather than heating by exothermic releases, reduces the binding energy by physical processes; therefore, humidity remains bound.
