Concept:The phenomenon of ice cubes fusing together under pressure is called regelation. It fundamentally relies on the unique intermolecular forces of water.
Formula:Not applicable.
Solution:- When pressure is applied to the ice cubes, the melting point of ice slightly decreases, causing a very thin layer of water to melt between them.
- When the pressure is released, this thin layer of water immediately refreezes.
- The refreezing process perfectly aligns the water molecules to form highly stable, rigid Hydrogen bonds between the two previously separate blocks, fusing them into one continuous lattice.
Why other options are incorrect:While dipole forces exist, hydrogen bonding is the specific, dominant force dictating the crystal lattice structure of solid ice. Covalent bonds do not form between distinct water molecules.
Quality & Fidelity Assurance:
Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
