Question

On a flight to Europe, you notice that the packages of peanuts are puffed up. Why?

1.) They were packaged at a higher pressure on the ground, thus causing the gas inside the packages to expand in the sky where the jet is at a lower pressure.

2.) The packages are puffed up on the ground due to overinflation with helium. This type of packaging provides extra buoyancy for aircrafts.

3.) The peanuts have greater velocities at high altitudes, thus causing the peanuts to exert more force on the packaging.

4.) The air in the jet is approximately ten times hotter than on the ground, thus increasing the temperature of the gas in the packages.

5.) The jet is over-pressurized at high altitudes, thus causing the gas inside the packages to expand.

Explanation / Answer

They were packaged at a higher pressure on the ground, thus causing the gas inside the packages to expand in the sky where the jet is at a lower pressure.

because pressure decreases with altitude and hence when flight in on travel at certain height pressure will low when compared to ground level at which the packages is packed so gas will expand at lower pressure leading to puff of package
