RANCIDITY:-
RANCIDITY IS THE EXAMPLE OF OXIDATION
IT MEANS SPOILING OF FOOD WHICH IS KEPT UNCOVERED
IT HAPPENS MAINLY IN SUMMERS
EX:-
HERE'S A REAL LIFE EXAMPLE

Rusting:Rust is an iron oxide, a usually red oxide formed by the redox reaction of iron and oxygen in the presence of water or air moisture. Several forms of rust are distinguishable both visually and by spectroscopy, and form under different circumstances. Rust consists of hydrated iron(III) oxides Fe2O..
Corrosion: It is the process in which metals are slowly eaten up by the action of air moisture or chemicals. For example rusting is a form of corrosion in which iron is eaten up by the action of air and moisture and a reddish brown coating of iron oxide is formed as shown in the following chemical reaction.
Rancidity: When the substance containing oils and fats are exposed to air they get oxidised and become rancid due to which their smell, taste and colour change. This process is known as rancidity. For example when a when butter is kept open for a long time then its smell and taste gets changed.
