Why does frost form patterns?

Answer: Crystal growth follows physics

Ice crystals grow randomly — Wrong. Growth isn't random—highly structured! Water molecules form hexagonal lattices following thermodynamic rules, creating fractal patterns.

Temperature variations pattern it — Wrong. Temperature affects growth rate, but basic patterns from hexagonal ice crystal structure—molecular bonding geometry.

Crystal growth follows physics ✓ — Correct! Fractal crystal growth! Frost patterns form from: (1) Water vapor contacts cold surface below freezing. (2) Deposition—gas directly to solid (bypasses liquid). (3) Ice crystals: hexagonal structure (H₂O molecular bonding). (4) Branching growth—faster at tips (more exposed surface). (5) Self-similar fractal patterns (dendrites). Window frost: feather-like patterns. Each pattern unique—depends on temperature, humidity, surface imperfections. Similar to snowflakes—hexagonal symmetry. Thermodynamics + crystal physics create art!
