Hikers have noticed that a sealed bag of potato
chips puffs up when taken to the top of a mountain.
Suppose that at the valley floor below, the air
pressure is 1.0 atm, temperature is 25°C, and the
volume of the chip bag is 0.985 L. At the top of the
mountain, the temperature is 22°C and the chip
bag has puffed up to 1.030 L.

What is the air pressure on top of the mountain?
atm

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?

give me abc and i will get it for u.
