Why does pressure melt ice?
Chang Q. Sun
TL;DR
This paper explains how pressure affects ice melting by altering molecular bonds, specifically through Coulomb repulsion that changes bond lengths and reduces melting temperature.
Contribution
It introduces a molecular-level explanation of pressure-induced melting in ice based on bond length changes and Coulomb interactions.
Findings
Compression shortens O:H nonbond
Elongation of H-O bond lowers melting point
Coulomb repulsion drives bond length changes
Abstract
Compression shortens the O:H nonbond and lengthens the H-O bond simultaneously via O:H-O Coulomb repulsion. The energy loss of the elongated H-O bond lowers the melting point.
