← ScienceWhich configuration change increases hydrogen bond strength between water molecules in liquid water?
A)Lowering the water temperature✓
B)Increasing the applied pressure
C)Adding a hydrophobic solute
D)Raising the solution's ionic strength
💡 Explanation
When water temperature decreases, the average kinetic energy of the molecules drops, reducing thermal motion disrupting hydrogen bonds and allowing them to align more optimally between adjacent molecules. Therefore, hydrogen bond strength increases rather than decreases which result from increased temperature, steric hinderance, or charge disruption.
