1 point
Carbon dioxide gas
Nitrogen gas
Oxygen gas
Neon gas​

Answer 1

Answer:

nitrogen gas is used in the storage of fat and oil containing food for a long time

Answer 2

The gas that is used in the storage of fat and oil-containing foods for a long time is "Nitrogen gas". (option 2nd)

• The food items containing oil and fat, become rancid on coming in contact with the oxygen. In such a condition, there may be observed some change in color, odor, and even taste of the food, and food items like these are not advised to be consumed.
• It happens due to the reaction of the molecules of oxygen with oil and food.
• Using nitrogen gas, also sometimes helium, creates an unreactive environment for the food, letting oxygen not react with food, thus preventing the rancidity.

Thus, among the given options, Nitrogen gas (option second) is used in the storage of fat and oil-containing foods for a long time.
