A packet of potato chips is flushed with an inert gas before sealing. Why is this specific component of air used instead of ordinary atmospheric air?
  1. Nitrogen prevents the chips from reacting with oxygen and turning rancid.
  2. Carbon dioxide keeps the chips cold and crunchy.
  3. Argon makes the packet lighter for easy transportation.
  4. Oxygen keeps the micro-organisms inside the packet alive.

Solution

Nitrogen is chemically inactive and replaces oxygen inside the package, preventing oxidation of fats and oils which would otherwise spoil the taste and smell.
