Among the gases mentioned if the list of options, nitrogen, oxygen,
methane and water vapor, water vapor has the greatest effect on the
weather conditions. The reason is that the humidity of the gases can
change considerable and given that H2O molecules will replace (or be
replace by) N2 and O2 molecules, and due to the difference in the molar
masses of H2O and the other two gases, the molar mass of the mixture
(air) will change considerably and this will cause changes in the
atmosphere pressure.
The lungs recoil to force the air out of the lungs. The intercostal muscles relax, returning the chest wall to its original position. The diaphragm also relaxes, moving higher into the thoracic cavity.
