Understanding Phase Transitions Through Energy and Randomness 2025
Phase transitions reveal nature’s elegant balance between energy, order, and randomness. From water freezing into ice to the emergence of stable crystal structures, microscopic configurations dictate macroscopic behaviors—like why ice floats, a phenomenon rooted in energy-minimized, ordered disorder. This journey into frozen water’s molecular architecture illustrates how thermodynamic principles shape the physical world around us.
The Molecular Geometry of Frozen Water: How Structure Defies DensityAt the heart of ice’s buoyancy lies its hexagonal lattice, formed when water molecules crystallize under freezing conditions. Each molecule aligns via hydrogen bonds into a rigid, open-framework structure—unlike the dense, disordered arrangement of liquid water. This rigid lattice reduces molecular density despite losing kinetic energy,
