Boiling water - Physical (the water is just changing states)

Dissolving salt in water - Physical ( the salt is just ionizing, if you boil the water off, the salt will reform in its solid state)

Rusting of Iron - Chemical (Fe + O2 --> FeO2)

Evaporation of water - physical (see boiling)

Cooking an egg - chemical

Burning Wood - chemical (combustion reaction)
