Microscopic Origin of the Surface Tension Anomaly of Water
We investigate the hydrogen bonding percolation threshold of water molecules at the surface of the liquid vapor interface. We show that the percolation temperature agrees within statistical accuracy with the high-temperature inflection point of the water surface tension. We associate the origin of this surface tension anomaly of water with the sudden breakup of the hydrogen-bonding network in the interfacial molecular layer.
