← ScienceWhich mechanism causes increased water viscosity at low temperature?
A)Hydrogen bond formation increases✓
B)Brownian motion energy increases
C)Ionic dissociation equilibrium shifts
D)Covalent bond cleavage increases
💡 Explanation
Cooling increases hydrogen bonding among water molecules, because the lower kinetic energy allows hydrogen bond formation rather than being disrupted by molecular motion, therefore viscosity increases, rather than decreases as molecular motion slows.
