← ScienceWhich consequence results when water exceeds supercritical temperature?
A)Hydrogen bonds weaken; viscosity decreases✓
B)Covalent network forms; increased rigidity
C)Ionic lattice solidifies; decreased mobility
D)Metallic bonds emerge; electrical conduction
💡 Explanation
Water above its critical point no longer exhibits liquid-vapor distinction because thermal energy overwhelms intermolecular forces. The hydrogen bonds weaken, therefore viscosity drops sharply, rather than forming rigid covalent or ionic networks, since molecules become more independent.
