a. corrosion of aluminum metal = chemical process

b. Melting of ice = physical process

c. Pulverizing an aspirin. = physical processd. Digesting a candy bar. = chemical process

e. Explosion of nitroglycerin. = chemical process

f. Milk turning sour. = chemical process

g. Burning of paper. = chemical process

h. Forming of frost on a cold night. = physical process

i. Bleaching of hair with hydrogen peroxide. = chemical process

j. A copper wire is hammered flat. = physical process
