On a flight to Europe, you notice that the packages of peanuts are puffed up. Why? 1. The jet is over-pressurized at high altitu
hodyreva [135]

Answer:

The correct answer is;

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.

Explanation:

According to Boyle's law, the pressure of a given mass of gas is inversely proportional to it volume at constant temperature

P₁·V₁ = P₂·V₂

At the factories, the peanuts are packaged at atmospheric conditions whereby P₁ = 1 atm, however, the pressure of the air in the atmosphere decreases with altitude as such the pressure in the airplane jet is about a fraction of hat on the ground by about a factor of 0.7.

Therefore P₂ = 0.7 atm and we have

V₂ = P₁·V₁/P₂ = 1 atm×V₁/0.7 atm = 1.43·V₁

The volume increases at high altitudes

Noble Gases (18): (Name all noble gases)
Paul [167]

Answer :

  • The Noble gasses are Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), Radon (Rn).
  • When air is cold, Oxygen liquefies first at -182^oC. N_2 liquefies at -195^oC. About 1% of the air is still gas composed of the noble gas Argon, Ar.
  • One noble gas was discovered on the sun. It’s spectrum was identify first. This is Helium, He.
  • One of noble gas is radioactive and seeps up your basement floors and walls. It is Radon, Rn.
  • This noble gas is used in electronic flashes and other bright lights. It is Xenon, Xe.
  • This noble gas is best known for its orange color in gas discharge tubes. It is used for signs that bear its name. It is Neon, Ne.

A friend tells you that plants grow and gain mass only because of the nutrients they pull out of the soil. It this statement tru
Nutka1998 [239]
The statement that the friend made is not true. most of the mass of the plant is from carbon. the carbon comes from carbon dioxide which is used during photosynthesis. the left over carbon from photosynthesis is used to to help the plant gain mass. there is a process for this which is called cellular respiration
