It is recommended to use airtight container for storing oil for long time.​

Answer 1

Answer:

It is recommended to use air tight container for storing oil for long time because: ⇒ When oil comes in contact with air, it undergoes air oxidation. ⇒ This can make the oil rancid (a foul smell). ⇒ Thus, it is advised to use air tight container for storing oil to prevent it from exposure of air.
