Side-by-side comparison of liquid-to-gas (evaporation) vs solid-to-gas (sublimation) phase transitions.
| Feature | Evaporation 💧 | Sublimation 🧊 |
|---|---|---|
| Initial State | Liquid | Solid |
| Final State | Gas (Vapor) | Gas (Vapor) |
| Energy Required | Latent Heat of Vaporization | Latent Heat of Sublimation (Higher) |
| Occurrence | Only at the surface of the liquid | Only at the surface of the solid |
| Temperature | Can happen at any temperature below boiling point | Happens when pressure is below the triple point |
| Bonds Broken | Loosened intermolecular bonds | Rigid crystal lattice bonds + intermolecular bonds |
| Common Example | Puddle drying up in the sun | Dry ice turning into fog |
