here is your answer ...

● Corrosion => The slowly eating up of surface of metal due to continuous action of moisture and air is known as corrosion . For example : silver articles corroded with a black layer of silver sulphide (Hg2S ).

#corrosion of iron article is known as rusting . it's formula is Fe2O3. x H2O.

● Rancidity : The process of areal oxidation of fats and oil resulting into bad smell and bad taste is called Rancidity .

# As we further noticed that when oil and fats containing food left for a long time in atmosphere it starts producing foul smell and bad taste . this is only due to Rancidity .

To prevent it food materials are kept in refrigerators and flushed with nitrogen .
