Nitrogen and Oxygen.
The turbinates at the top of the nose are moist and exist to moisten air as it enters the respiratory tract.
The top.
Noble gases can be found in group 8 on the periodic table (column farthest to the right). They have 8 valance electrons in their outer shell and therefore do not react with anything. This made it hard for scientists to discover them.
The densities of the noble gases increase with increasing molecular mass. The increase in density is due to the increase in atomic mass. Helium is about one seventh the density of air and can be used in balloons and lighter-than-air craft. Xenon is about five times the density of air.
Air pressure at the top of a chimney is lower than at the bottom due to the principles of buoyancy and the stack effect. As warm air rises, it expands and becomes less dense, creating lower pressure at the top compared to the cooler, denser air at the bottom. This difference in pressure encourages the upward flow of air and gases, which is essential for efficient ventilation and combustion in systems like fireplaces or furnaces.
1) Most likely, you want to obtain pure gases, so by minimizing the amount of air you have in the top, you will maximize the purity of the collected gases 2) Some gases may react with air. Thus, minimizing contact with air assures you get the product you desire.
The top two gases found in the Earth's atmosphere are nitrogen, which makes up about 78% of the atmosphere, and oxygen, accounting for approximately 21%. Together, these two gases dominate the atmospheric composition, with trace amounts of other gases such as argon, carbon dioxide, and water vapor making up the remainder. Nitrogen plays a crucial role in various biological processes, while oxygen is essential for respiration in most living organisms.

Warm gases and warm fluids rise to the top. Same principle that makes hot air balloons fly.
Air is made up of 78% nitrogen, 20.95% oxygen, 0.93% argon plus traces of other gases.
The 1990 Buick LeSabre air conditioner recharge valve can be found on top of the air conditioning compressor. The air conditioner recharge valve will have a blue top.
The biome most likely to be found on the top of a very tall tropical mountain is the TUNDRA

The air conditioning port can be found on the top and the bottom of the air conditioning compressor. There are two air conditioning ports.
The intake air temperature sensor can be found on the top of the air intake manifold. The temperature sensor should be labeled as such.
