A physical process is a process which do not change the substance structure only its shape or phase is changed. On the other hand, a chemical process involves the formation of new substances.

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
