On a flight to Europe, you notice that the packages of peanuts are puffed up. Why?1. The peanuts have greater velocities at high altitudes, thus causing the peanuts to exert more force on the packaging.2. The jet is over-pressurized at high altitudes, thus causing the gas inside the packages to expand.3. The air in the jet is approximately ten times hotter than on the ground, thus increasing the temperature of the gas in the packages.4. The packages are puffed up on the ground due to overinflation with helium. This type of packaging provides extra buoyancy for aircrafts.5. 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.

Freon-12 (CF2Cl2) is commonly used as the refrigerant in central home air conditioners. The system is initially charged to a pressure of 4.8 atm. Express this pressure in each of the following units (1 atm = 14.7 psi).b. torr

High-pressure liquid chromatography (HPLC) is a method used in chemistry and biochemistry to purify chemical substances. The pressures used in this procedure range from around 500 kilopascals (500,000 Pa) to about 60,000 kPa (60,000,000 Pa). It is often convenient to know the pressure in torr. If an HPLC procedure is running at a pressure of 2.90 x 10 8 Pa, what is its running pressure in torr? Express the pressure numerically in torr.
