Question

Name the gas that can be used for the storage of fresh samples of chips for a long time.

Answer 1

Nitrogen$\left({\mathrm{N}}_2\right)$ gas is used to store fresh samples of chips for a long time.

The function of Nitrogen $\left({\mathrm{N}}_2\right)$ gas

Oil becomes rancid when it comes into contact with air or atmospheric oxygen. The oxidative deterioration of oil is known as rancidity. We can prevent oil from becoming rancid if we avoid exposing it to air. We can use helium or nitrogen to coat the surface of oil for this purpose.

Therefore, the gas that can be used for the storage of fresh samples of chips for a long time is Nitrogen$\left({\mathrm{N}}_2\right)$ gas as it prevents the rancidity of oil.
