Answer:

| Process | Object | Examples |

|---------------|-----------------|---------------------------|

| Evaporation | Water | Puddle, Wet clothes, Pool |

| | Alcohol | Hand sanitizer, Perfume, Rubbing alcohol |

| | Acetone | Nail polish remover, Paint stripper, Cleaning solvent |

| Sublimation | Dry ice | Solid carbon dioxide, Fog machine, Food preservation |

| | Camphor | Mothballs, Medicinal uses, Insect repellent |

| | Iodine | Sublimation demonstrations, Laboratory uses, Starch indicator |
