← ScienceWhich risk increases when a desiccant such as silica gel undergoes complete moisture absorption?
A)Reduced adsorption efficiency is subsequently observed✓
B)Reversed phase transition spontaneously escalates sharply
C)Increased heat transfer via conduction follows
D)Higher structural degradation lowers stability rating
💡 Explanation
Reduced adsorption occurs because saturation negates the *capillary condensation* mechanism within the gel, therefore no further water molecules are drawn, rather than phase change because the water has already condensed into the gel's capillaries causing deactivation.
